Harvard Study Reveals: Planetary Health Diet Can Extend Your Life and Save Earth Too

Friday, June 14, 2024

A study by Harvard T.H. Chan School of Public Health highlights the dual benefits of the Planetary Health Diet (PHD), which not only reduces the risk of premature death by up to 30% but also significantly decreases environmental impacts. The PHD, which advocates for a varied diet of minimally processed plant foods with limited meat and dairy, is shown to lower greenhouse gas emissions, fertilizer needs, and cropland use, demonstrating the deep connection between dietary choices and both human and planetary health.Adhering to the Planetary Health Diet significantly reduces the risk of premature death and environmental impact, including lowered rates of major diseases and reduced greenhouse gas emissions and land use.According to a new study from Harvard T.H. Chan School of Public Health, adopting a healthy, sustainable diet, as outlined in the 2019 EAT-Lancet report, can significantly reduce both the risk of premature death and environmental impact. This landmark study is the first to directly assess the effects of following the dietary guidelines proposed in the report, which recommends a diverse intake of minimally processed plant foods while permitting limited amounts of meat and dairy. The researchers refer to this recommended diet as the Planetary Health Diet (PHD).The study was recently published in The American Journal of Clinical Nutrition.“Climate change has our planet on track for ecological disaster, and our food system plays a major role,” said corresponding author Walter Willett, professor of epidemiology and nutrition. “Shifting how we eat can help slow the process of climate change. And what’s healthiest for the planet is also healthiest for humans.” While other studies have found that diets emphasizing plant-based foods over animal-sourced foods could have benefits for human and planetary health, most have used one-time dietary assessments, which produce weaker results than looking at diets over a long period of time.The researchers used health data from more than 200,000 women and men enrolled in the Nurses’ Health Study I and II and the Health Professionals Follow-Up Study. Participants were free of major chronic diseases at the start of the study and completed dietary questionnaires every four years for up to 34 years. Participants’ diets were scored based on intake of 15 food groups—including whole grains, vegetables, poultry, and nuts—to quantify adherence to the PHD.Health and Environmental Benefits of the PHDThe study found that the risk of premature death was 30% lower in the top 10% of participants most closely adhering to PHD compared to those in the lowest 10%.

Chronic health problems amplify heat risk in the Rio Grande Valley

The deaths of two elderly siblings and their 60-year-old caretaker at first mystified Brownsville. Extreme heat is a quiet but growing threat for Rio Grande Valley residents with chronic health conditions.

Something seemed amiss when police officer Oscar Lizarraga arrived at the Conquistador Apartments. Maria Ester Singh hadn’t yet paid that month’s rent, and the apartment manager said that was unusual. Singh’s daughter, who lives outside Houston, hadn’t heard from her since April. She asked a cousin in Brownsville to check in on her. Now it was May 8, and no one answered a knock at the door of unit 1012, which was latched from the inside. Joaquin Galvan, 82, Maria Trinidad Galvan, 78, and Singh, 60, lived in the apartment complex on Billy Mitchell Boulevard with three small dogs. Singh was the personal care attendant for Joaquin, her father, and Maria Trinidad, her aunt. Lizarraga checked the windows and doors for signs of forced entry. Finding none, he pried the door open. He saw a body slumped on the floor. He asked Maria’s cousin and the apartment manager to wait outside. The three family members had been dead for days. A pathologist attributed the deaths to complications of diabetes and extreme heat. “Multiple floor fans were in operation,” according to the autopsy report. “The air conditioner was reportedly not in operation and the inside thermostat displayed a reading of 88 F.” Temperatures had been in the 90s recently, and on the day the bodies were found, the mercury would hit 104. Police said the AC was turned on when they entered the apartment. “Whether or not it was functioning properly is something that was undetermined,” a Brownsville Police Department spokeswoman said. Crime scene tape hangs from the doorway of unit 1012 at the Conquistador Apartments, where three family members were found dead on May 8. Chris Lee / San Antonio Express-News Either way, the pathologist’s conclusion was clear: the heat, along with their chronic medical conditions, was enough to kill all three family members. The case illustrates the latent threat of extreme heat in deep south Texas and the disproportionate impact of climate change and high temperatures on the elderly. It also shines a light on the outsized role isolation plays in heat-related deaths, especially among the elderly in America, one-quarter of whom are considered “socially isolated,” according to the National Academy of Sciences. The Rio Grande Valley has elevated rates of diabetes, heart failure and other chronic conditions. Now the population faces an additional threat: hotter days and nights, and more of them. Poverty and lack of health insurance magnify the risk of heat illnesses and deaths. Other aggravating factors: jobs that require people to withstand long hours in the hot sun and electric bills too high for low-income families to pay. “It’s 104 degrees and frequently one of the hottest parts of the United States,” said Dr. Ivan Melendez, the health authority for Hidalgo County, part of the Rio Grande Valley. “It’s a tremendous amount of cofactors coming together… It’s just a total nightmare. It’s a perfect storm.” Danielle Arigoni, an urban planner and author of “Climate Resilience for an Aging Nation,” said the elderly are often left out of climate change and disaster planning, even though they die at disproportionate rates during natural disasters. “How many more times do we have to see these headlines before we do things differently?” she said. “This is a tragedy. Our older adults deserve better.” “Completely preventable” Maria Trinidad and her brother Joaquin had spent their whole lives in Brownsville. Their first home was just a few miles from the Conquistador Apartments. The Galvan family lived at 1054 Roosevelt Avenue in 1950 when interviewed for that year’s census. Their father, Alberto, was born in Brownsville and worked as a longshoreman at the port. His wife, Maria Trinidad, was from the town of Cuero, southeast of San Antonio. By 1950 they had seven children. Joaquin was the third, born in 1941, and Maria Trinidad the fifth, born in 1945.  Joaquin wed Minerva Cervantes in 1964 when he was 22. The couple continued to live at the house on Roosevelt, where they had four children of their own. The Brownsville Herald reported the death of a “baby Alberto” in 1973. It’s unclear how Joaquin and Maria Trinidad wound up at the Conquistador Apartments or how long they had been there. Their neighbors in the Conquistador Apartments in Brownsville rarely saw Joaquin Galvan, 82, his 78-year-old sister and his 60-year-old daughter. Chris Lee / San Antonio Express-News Family members did not respond to requests for interviews. But publicly available records paint a picture of a family that scattered across Texas and beyond, likely leaving few relatives in Brownsville to help the aging siblings. The cousin who called the police told them she had not spoken with them in more than two years.  Investigators have not determined the exact sequence of events leading up to the deaths. Months later, crime scene tape still hung from the doorway of the apartment. Brownsville police said their investigation is ongoing, and added, without elaborating, that they are looking into the possibility of elder abuse.  The Conquistador Apartments, a cluster of unremarkable two-story buildings painted blue and light orange, is managed by an Austin company. Rents for one-bedroom apartments start at $699. The unit where the three family members died is a two-bedroom and is currently listed for rent at $879 a month. The apartments at Conquistador have central air conditioning, and the walkways are shaded by trees. When officer Lizarraga entered unit 1012 on the morning of May 8, he found Singh’s body in a front room and the bodies of Joaquin and his sister in two back bedrooms. The siblings both appeared to have fallen out of bed. All three bodies were in a state of decay. Lizarraga called animal control to take control of the three small dogs barking at his feet. He called a Justice of the Peace, detectives and crime scene investigators. Employees of two funeral homes arrived by midday. The bodies were transported for autopsies. Investigators started interviewing neighbors and family members. The autopsy report said the outdoor temperature was 85 degrees and the heat index was 96.8 when the family was found at about 9 a.m. that day. Heat index combines relative humidity and air temperature to capture how hot it feels under certain weather conditions. The pathologist determined that heat contributed to all three deaths. Singh died of diabetes ketoacidosis (DKA), complicated by heat exposure. DKA develops when the body doesn’t produce enough insulin, and acids known as ketones build up in the bloodstream. Without insulin, Singh would have declined rapidly until she entered a diabetic coma. The combination of high blood sugar and heat were fatal. Maria Trinidad died of diabetes mellitus, hypertension and hypothyroidism complicated by heat exposure. Joaquin died of diabetes mellitus, hypertension and elevated cholesterol, complicated by heat exposure. “This family’s death was completely preventable,” said Jeff Goodell, an Austin-based journalist and author of “The Heat Will Kill You First.” He pointed out that Texas has made no statewide effort to map vulnerable communities or reach the populations most endangered by excessive heat. He drew a contrast to the extensive governmental warnings and preparations that precede the arrival of a tropical storm or hurricane. “This is what happens when you have a government, local and state, that is not taking this risk seriously,” Goodell said of the Brownsville deaths. “Numbers that we have not seen before” As diabetics, Joaquin, Maria Trinidad and Singh were at greater risk from the heat. The damage diabetes does to nerves and blood vessels inhibits the body’s cooling mechanisms. When a person’s blood sugar spikes, they are also at risk of dehydration because they will urinate excessively to expel the blood sugar.  Jose Vazquez, an internist in the Rio Grande Valley, explained that a diabetic’s “temperature regulation system is already impaired.” He said medications to treat diabetes can further blunt the body’s response to heat. “We are exposed to high temperatures all year round,” Vazquez said. “However, over the last few years we have reached numbers that we have not seen before – 110, 112 degrees at the peak.” Left: Jose Vezquez, an internist in the Rio Grande Valley. Right: Dr. James Castillo, the health authority for Cameron County. Chris Lee/San Antonio Express-News One in three Rio Grande Valley residents has diabetes, about double the national rate, according to recent research. Many Valley residents with diabetes never receive a diagnosis and the disease goes unmanaged.  Many people with diabetes, especially those without health insurance, don’t seek treatment until the disease is already advanced. Brownsville is the seat of Cameron County, where 29% of residents are uninsured and another 26% are on Medicaid or other income-based public insurance. Without treatment, otherwise preventable wounds and infections lead to amputations. The Rio Grande Valley, which encompasses Cameron, Hidalgo, Starr and Willacy counties, has higher rates of diabetic amputations than the rest of the state. Joaquin Galvan was a below-the-knee amputee, although it could not be determined whether his diabetes was the reason. He used a wheelchair and was functionally immobile. His sister Maria Trinidad had congestive heart failure and hyperthyroidism in addition to diabetes. The siblings required round-the-clock care. Singh was employed by two home health care agencies as a personal care attendant for her father and aunt. She also was managing her own diabetes. Once Singh was incapacitated, the elder siblings may have been unable to seek help. Dr. James Castillo, a hospice doctor and health authority for Cameron County, said many of his patients with complex health problems prefer to be treated at home. He often has to consider whether home is a safe environment. Does the AC work? Is there a heat wave? Will the electricity stay on to keep medical equipment running? “You have a very large population of medically fragile people,” he said of the Rio Grande Valley. “And in a crisis, fragility shows.” “Don’t really know who they were” Arigoni found that in disasters such as Hurricane Katrina, Texas’ Winter Storm Uri in 2021 and the Oregon heat dome the same year, elderly people die in disproportionate numbers. She said emergency management plans often account for elderly people at nursing homes but overlook those who are socially isolated and living at home, as the Galvans were. “You see it time and time and time again, predictably, that older adults are dying at double, triple, quadruple the rate of other people in disasters,” she said. Joaquin, Maria Trinidad and Maria Ester seemed to have made few impressions on their neighbors. Oralia Favata, 68, who lives a few doors down from their apartment, said she had never met them but would notice flyers and mail piling up outside the door.  Oralia Favata, 68, lives a few doors down from unit 1012 at the Conquistador Apartments but she knew nothing about the people who lived there. Chris Lee / San Antonio Express-News “I never saw anybody come in or out or visit them,” she said. “I don’t really know who they were.” On May 8, she watched a woman break down in tears outside the Galvans’ apartment. Favata said a relative of the Galvans gave her a bag of left-over dog food from the apartment before driving back to Houston.  Other neighbors repeated similar stories. Several said they learned only after the fact who the Galvans were.  The Sunset Memorial Funeral Home took care of the family’s remains but no funeral services were held. One relative wrote on an online memorial page for Maria Trinidad that she would miss watching telenovelas with her. “I will miss you forever Tia Trine.” “You can’t live here (without AC) … period” Brownsville has always been hot and humid. But temperatures rarely reached 100 degrees in the 1940s and 1950s, when the Galvans were growing up. Air conditioning was not yet widespread in the Rio Grande Valley. In old adobe houses, people would open the doors at night and let cross-ventilation cool their homes. Over the span of the Galvan siblings’ lifetimes, that changed. As temperatures creeped up, air conditioning became ubiquitous.  The five hottest summers in Brownsville since record keeping began in 1878 have all been since 2018. 2023 was the hottest year on record. The 40 days of 100-degree heat in 2023 shattered the previous record of 12 days. So far in 2024, there have been 7 days of 100 degree heat, the fifth highest annual total. Dr. Ivan Melendez, the Hidalgo County health authority, grew up in the Rio Grande Valley in the 1960s and ’70s, when air conditioning was a luxury. Chris Lee / San Antonio Express-News “I remember when we were kids in the 1960s, 1970s, hardly anybody had air conditioning,” said Dr. Ivan Melendez, the Hidalgo County health authority. “We couldn’t afford it. It was really more of a privilege. “Now if you don’t have air conditioning in the Valley, you can’t live here,” he said. “You cannot survive the summer here without air conditioning. Period.” Extreme heat is starting earlier in the year. May 2024 was the hottest May on record in the city. Overnight, the heat index often stayed above 90 degrees during May. High nighttime temperatures prevent the body from cooling off and recovering from daytime heat. As of early September, Brownsville EMS had responded to 42 heat-related emergencies during summer 2024. Paramedic Hector Martinez estimated about 100 additional calls were most likely heat-related.  South Texas Health System’s acute care and emergency departments in the Rio Grande Valley saw a spike in heat-related illnesses last year. From 2020 to 2022, the system recorded fewer than 200 heat-related illnesses a year. In 2023, they treated 325. By the end of August this year, the network had surpassed last year’s total of heat-related illnesses. The Texas Department of State Health Services uses death certificates to determine the number of deaths attributed to heat in Texas by county. When 10 or fewer heat deaths are recorded in a county, the exact number is withheld to protect confidentiality. Most years in Cameron County, the number has been below 10, according to data obtained by the Texas Tribune. In 2023, the total jumped to 11, including deaths where heat was a contributing factor. Two were migrants—a 44-year-old Mexican and a 32-year-old Guatemalan who succumbed to “environmental heat exposure” after crossing the border. The 2023 total included a 43-year-old man with Down syndrome who died in a house without air conditioning. Data for 2024 is not yet available. Medical professionals say death certificates present an incomplete picture of heat-related fatalities. Physicians list the direct cause of death—a heart attack, a drug overdose—but often do not know about contributing factors.  Autopsies can yield more information. In Cameron and Hidalgo Counties, Justices of the Peace determine when to have a forensic pathologist conduct an autopsy. (In more populous counties, a medical examiner’s office makes that decision.)  Melendez said that under this system, a death certificate may be completed by a doctor, or a Justice of the Peace, or a coroner. The role of heat is not always considered. “Everyone has a different opinion,” he said. “And a different level of expertise.” Alone in their moment of crisis As a community paramedic in Brownsville, Hector Martinez keeps a close eye on the number of 911 calls and where they are coming from. Community paramedics provide preventive as well as routine medical care to minimize repeat hospital admissions in under-served populations. There’s a clear pattern to heat-related emergencies, he said. Most of those calls come from low-income neighborhoods. Martinez said the most common such emergency involves a man who works outdoors, or in a confined space such as a restaurant kitchen, and underestimates the toll of the heat. “They work landscaping. They work in restaurants—cooks, waiters, waitresses,” he said. “They do manual labor, they’re builders.” On a September afternoon, Martinez drove the backstreets of Brownsville’s Southmost neighborhood with the familiarity of a taxi driver. More than three in 10 residents in this ZIP code (78521) live in poverty, according to census data. The median household income is $38,000.  More than five months after three family members were found dead inside unit 1012 at the Conquistador Apartments in Brownsville, crime scene tape still hangs from the doorway. Chris Lee / San Antonio Express-News A $100 repair to an air conditioner could help keep a low-income resident out of the emergency room. Martinez will find a charity, church or nonprofit to help. “We don’t have a budget for it,” he said. “So we try and find people.” The Area Agency on Aging and Rotary Clubs are some of his most reliable partners. But their funds run out every year.  The federally funded Low Income Home Energy Assistance Program helps people below the poverty line pay for heating and cooling. But in states such as Texas, with large low-income populations and extended periods of extreme heat, the funds cover a small fraction of those eligible. The Hidalgo County agency that disburses utility assistance funds is closed to applications because of high demand. Christopher Basaldú, a co-founder of the South Texas Environmental Justice Network, said Brownsville should open more cooling centers. The organization hands out bottled water at its downtown Brownsville office, which an overtaxed window unit struggles to keep cool during the summer. “Climate change is happening. The heat is going up and it’s becoming more relentless,” he said. “People are choosing to not run their air conditioners as part of ways of saving money.” The City of Brownsville did not respond to questions about its preparedness for extreme heat. Nor did city commissioner Bryan Martinez, who represents the area of the Conquistador Apartments, or Cameron County Judge Eddie Treviño. The Community Lighthouses in New Orleans have been held up as a model for protecting vulnerable populations from the heat. These are churches and other community spaces equipped with solar power to keep the lights and air conditioning running during natural disasters or heat waves. The Lighthouses are dispersed throughout neighborhoods within walking distance of vulnerable populations. Staff knock on doors to inform residents about their services before disaster strikes. Ailing and isolated, the Galvans were alone in their moment of crisis.  After they died, there was no official response from the city or county. There was no public remembrance or reckoning. No obituaries were published. Neighbors were left to puzzle over how the family’s suffering went unnoticed. The Galvans’ surviving relatives mourned in private.  Another hot summer ran its course.

You can see all of the past episodes here.Listen below to our discussion with Diaz and subscribe to the podcast at iTunes or Spotify. Agents of Change in Environmental Justice · Laura Diaz on how social and environmental stress impact children’s healthTranscriptBrian BienkowskiLaura, how are you doing today?Laura Diaz I'm doing okay. How are youBrian Bienkowski I'm doing great. And where are you today?Laura Diaz I am in South San Francisco, which is close to the San Francisco International Airport.Brian Bienkowski Very cool. I love it out there. And you are from originally not far from there. So tell me a little bit about growing up in Northern California.Laura Diaz Yeah, so I grew up in the East San Francisco Bay Area, and specifically, it's like the geographic location where the watershed from the Sierra mountains meets the mouth of the San Francisco Bay, and it's beautiful. And just behind where the Bay is, there's these rolling golden hills. And because of the history that Pittsburgh has, which is my hometown, with the fossil fuel industry, and specifically during the Gold Rush, they were actually mining coal out there that laid the foundation for a polluting industry which persists today, and it's become one of the more affordable places in the San Francisco Bay area to live. And so I lived in between this corridor of polluting industry, right along that water, which included the Dow Chemical Plant, the power plant and several other toxic release facilities. And then on the other side of us was a highly trafficked freeway. And then we lived there until it was about four and then shortly after, we moved just over that same freeway, and the freeway was like legit our neighbors and the that whole corridor polluting industry was still an eye shot of where we lived. And those cities are largely known as commuter cities because they're so affordable. A lot of families move out there to raise their family, and that was true for my parents as well. So they commuted about an hour and a half, and so a lot of our childhood was spent largely unsupervised, and at some point, my parents decided to get us an inter-district transfer to the city where they worked. And so they worked in a city called wanna Creek, California, and that city is predominantly white and home to the uber rich. And I remember like, being at school and just feeling like I really didn't, like fit in. And it went beyond that, like kind of normal, like what I see with my son, where he's, like, trying to make friends and stuff. It went beyond that, like something just didn't fit. And I remember like, walking home from school, and I would have to walk through this outdoor plaza with stores like Neiman Marcus and Tiffany's and make my way to my dad's tailoring shop. And like, I remember opening the door, and I would get this like sense of relief, and I would feel like I could breathe again. And it was like home, and yet, I would see my dad on his hands and knees fixing the clothing of my classmates parents. And then every day we would take our trek back home. So we'd be going from this very affluent space, it was very green, a lot of open space back home, to this space where it's a lot of concrete, like again, we'd see, like, that whole polluting industry, and yet, like, I'd hop out of the car super excited, run to my neighbor's house and we'd be playing basketball for the rest of the evening. I have, like, so much love for where I grew up, and I feel like my work now is like. Of letter to my community, and I had this like daily reminder of the difference between wealth and poverty, between predominantly white communities and predominantly diverse communities.Brian Bienkowski Well, that's a really beautiful way to paint your hometown. I have to say, when I first looked it up, I was like, I did not know Laura was from Pittsburgh. When I met her, she seemed like she was from the West Coast, so I did not know that there was a Pittsburgh California. But thank you so much for painting that picture. And you, you know, you've mentioned this kind of industrial backdrop and maybe some social dynamics and racial dynamics at school that were uncomfortable. I'm wondering where along the way you became aware or interested in kind of the concept of environmental justice and injustice?Laura Diaz Yeah. So, I mean, like those, like, big smokes stacks, like, what we see in pictures a lot when we see, like, read articles about environmental justice, like, that was the backdrop to my childhood. And yet, I had no idea that that, that I grew up in an environmental justice community, right? So I am a former high school science and math teacher, and there was a summer where I did a professional development program in the topic of sustainability. It had it was there that I met Karna Wong, and she's a faculty at Sonoma State University, and she absolutely changed my life. She gave a workshop on environmental justice, and she taught us about the principles of environmental justice, various frameworks of EJ and her and I, like, hit it off like it was, it was great. This is why I love, like, professional development programs, which we can talk about later. But she also showed me this database called CalEnviroScreen, and that is, it's basically a map of California, and it displays community exposures to pollution, health burdens and demographic characteristics. And that was the first time that I saw my community in bright red, because bright red means more burdens. And then I saw Walnut Creek bright green, and bright green is associated with less burdens, or under-burden. And it just was like this final puzzle piece of like, like, whoa, everything came together. And I like, understood that that feeling of like something wasn't right made so much sense by looking at that map, and I realized that environmental justice wasn't only something I like, loved learning about, it also impacted my life. I don't know, and I'm never going to know, if growing up in close proximity to these facilities is a reason why I have two chronic autoimmune diseases, but it does drive my work. And I think also, in addition to that, there was another educator fellowship that I was on, and I did that with Earthwatch. We were out at catalea Island, and we were studying Harmful Algal Blooms. And while we were out there, my mom called me, and she was like, I made it out, but paradise is on fire. And that was in 2018 and although she made it out alive, 85 folks did not, and that was the campfire. And over 13,000 homes were lost in one of those of my mom's and it's like, it's hard to talk about this, but it's like, because it's so deeply personal, right? But I remember flying home from that experience and waiting outside of the airport and it was raining ash, and those ashes included my mom's home. So it's just the impacts of climate justice, and environmental justice has hit me, personally, very hard, and I think more recently, I've been really thinking about the connection between wildfires in California, the fossil fuel industry and our inability to transition away fast enough, and how my community is going to continue to pay the price until we do so. And that really drives the work that I do. And like you can hear my voice shaking, but it's like I have so much passion to you, and it's so important. There's, there's an urgency to this work that's needed that I'm I'm not quite sensing enough in the academic spheres that I'm in now, but I hope to be a part of that driving force.Brian Bienkowski And I've been asking everybody this question before we get into some of your your research and your education, what is a moment or event that has helped shape your identity?Laura Diaz Yeah, okay, I think there's a couple I feel like we're getting into, like, the intense stuff in the beginning. So like, Sorry my voice is shaking, but also self-deprecating humor is how I get. So, I think the first thing that really, really impacted like who I am and how I moved through this world, was when I was in ninth grade, my dad and I had to go to the county courthouse, and it was the first time that I saw my brother handcuffed. And we were there to see him and be there for him while he was going to be sentenced for his first felony. And I remember the judge asked his family to stand up those, those of us who were there in support. And I was bawling as my I was seeing my hero like out there behind a glass wall in handcuffs, and I was like, barely could stand up, and I was just tears were just rolling down my face, and, like, for the longest time, I thought it was actually my fault that he got sentenced, because I couldn't keep it together, right? It was just I was I must have been around 13, right? a kid. And I think during my adolescence, I really developed this, like, strong understanding of the impact of oppression on the lives of children, and it really is the root of how I move through the work that I do. And I think also kind of on a more tender side, a moment that really has shaped who I am, is being my son's mom, and the day I became his mom was the most beautiful day of my life. And I tell him often how lucky I am to be his mom, and I like to say that my most proudest title is being soccer mom. And I do know too that like the most important thing I can do, personally and professionally is invest in my son and my family.Brian Bienkowski Awesome. Well, thank you so much for both of those very we will get you away from these, all of these that are pulling at your emotions. Maybe we'll circle back and we'll get emotional again, but thank you so much for opening up about that. I'm sure there are others who can relate. And when you talk about tears streaming down, I was hoping my my blue light glasses were hiding we're hiding mine on that so, so let's change gears a little bit. And you went to so you mentioned Sonoma State University, which is now recognized as a Hispanic serving institution, and you went there for your undergraduate degree. So we've had folks on talking about going to historically Black colleges and kind of the impact that had on them and a level of comfort and that it brought them. So I was wondering if you could talk about that experience and how going to a Hispanic Serving Institution benefited you?Laura Diaz Yeah, I, I remember the first week being on campus and like, being overwhelmed with this, like, sense of hope. And I think, and it was great, like I felt like, you're saying, I just felt like safe, that that uncomfortable, like unwelcoming feeling that I felt when I was going to schools in Walnut Creek was like gone. And I knew that I was believed in and supported by by the faculty. The commitment to teaching excellence at HSIs is so high, and that's really impacted my teaching philosophy now, and I understand firsthand what it means like to create a vulnerable learning environment and what it means to like not be in one, right? And because I was able to really thrive in this space, I majored in Molecular Cell bio. I double minored in Chem and in music. I was part of the chamber music orchestra, like I was, like, loving life. It was great. And also, my junior year, it started getting sick, and I was having to walk to school with a cane, and I ended up getting diagnosed with lupus, and during that diagnosis period that was really difficult. And despite that, I knew that the faculty were there for me. I knew my classmates were there for me, and they really helped me push through a really, really difficult time for me. And so I just, I feel very committed to what education means, what that means for social mobility, and that's stayed with me. And continue, I continue to work and partner with Sonoma State, which is, yeah, really great.Brian Bienkowski Yeah, what a great opportunity. Do you still play music?Laura Diaz I don't, but I need to. I played the piano. Oh,Brian Bienkowski no, no, that's that was my next question. That's very cool. Yeah, I am a musician. I play a whole variety of instruments. And I've said on the podcast before that it just it feels like it is that other side of the brain. It just feels so good to take some time to stretch the create creative legs every now and then, after staring at a computer for so long. So I'm always curious.Laura Diaz Yeah, I hear that, and hopefully this inspires me to, like, get it together,Brian Bienkowski get back to it. Yeah. Well, I'm sure you have as we're gonna get into it sounds like we have plenty going on, but I hope you find some time. So now you are studying air pollution, specifically particulate matter burdes in marginalized communities. So particulate matter is linked to negative health outcomes, and one of them that you focus on is mitochondrial dysfunction. So can you explain first, what mitochondria are and how air pollution may affect them?Laura Diaz So mitochondria are these fascinating little organelles that I've been spending several years thinking about. They're the site of chemical energy production of our cells, so they make the energy that our cells need in order to actually function properly. And they're really unique. So they have their own DNA or their own genome, and in that, within that, it codes for 13 proteins which are vital for the mitochondria to be functioning properly. And what's interesting about that is that they they lack these protective mechanisms that, like our nuclear DNA has, and so it makes them particularly vulnerable to situations where our cells are undergoing stress, and we see that mitochondrial function declines with aging and also with disease. And what I spend a lot of time thinking about is what mitochondrial function or dysfunction looks like in epithelial cells. And those are the cell types that we find in the lining of our mouth. They're in our lungs, and there's like outer barrier of our skin, so they come in contact with this, like wild outer world, and play this really important protective mechanism, and they they play a big role in detoxification. And so what happens when they're exposed to particulate matter? There's actually an increase in free radicals in our in the cell, and those are called reactive oxygen species, and those, if there's too many and there's an imbalance, those can cause mitochondrial dysfunction, and that's what I'm spending a lot of time thinking about.Brian Bienkowski So if these mitochondria are disrupted in some way by and I should say particulate matter is fine particulate pollution. This can come from anything from wildfires to traffic to to heavy industry, fossil fuel burning, if the mitochondria are disrupted, what kind of impact may that have on, let's say, developing children?Laura Diaz Yeah, so I, my research focuses on child health, and again, I'm really thinking about these epithelial cells and what's happening in relation to the exposure of, like, what you're saying with particulate matter and and when we see that mitochondrial dysfunction, it actually triggers a cascade of events to happen in the cell. So the cell tries to fix these problems when they come up, but when it's constantly having to fix these problems, that's when, that's when, like, long-term issues can can arise. And so what we see is that the this outer lining of cells can be really impacted by mitochondrial dysfunction, because they they get put in this like pro-inflammatory state, and so then they become really vulnerable to things like allergens. So what I'm studying, then, is, is that mitochondrial dysfunction playing a role in the development of diseases like eczema or rhinitis or asthma among children in frontline environmental justice communities.Brian Bienkowski So as part of this, you're also looking at adverse childhood experience known as ACES, which was a new acronym for me after I met you at the retreat. That was something I didn't know about. So in addition to the air pollution and mitochondrial dysfunction, you're looking at aces. So can you explain aces and why you feel it's an important part of including in this research,Laura Diaz ACES stands for Adverse Childhood eEperiences. In California, there's a lot of work being done on the public health end of things, and it's getting labeled as toxic stress. What it is is it's a survey with 10 questions that assesses a child's exposure to abuse, neglect and household challenges. And back in the 90s, there was a groundbreaking study that was done, and they found that exposure to ACES was associated with increased risk of death from seven out of 10 of the leading causes of death and so and there's been a lot more work done now, but I really want to invite us all in, like environmental health work and environmental justice, to be thinking about day to day stress, and that exposure to stress as an environmental exposure, just like we would think about particulate matter. And in order to understand the impact of oppression and the health impacts living in frontline communities, I think it's really important that we also include exposure to stress. And what I've found in my research is that exposure to ACES is associated with an increase in mitochondrial dysfunction and so, and I'm seeing that among a cohort of children, right? So it like the changes that becomes embodied in our cells happens pretty quickly. It can at least.Brian Bienkowski So you're seeing that not only. So if there are these environmental insults, and then you pile on kind of just day to day stress in a child's life, whether that's from inside or outside of the home, the combination of those, they're both doing bad things at the cellular level, to the kid or to a child, and setting them up for potential increased illness.Laura Diaz Yeah, and I think, like, I'm really thinking about the mitochondria a lot, obviously, but if we think about being in a state of stress, where we're in this, like fight or flight, like our physiological response, our cells have an increased need of energy, and when that happens over and over and over again, then the mitochondria is being overworked. And so understanding what's happening at the cellular level is also really important.Brian Bienkowski v really fascinating research. And I love the idea of thinking more about stress, and of course, with your research with kids, but even for adults. I mean, I think stress is such a kind of a silent killer. I mean, it just, it's so bad for our body, and yet, a lot of us kind of live with it, and it's part of our, part of our life, so it's really important to to remember that. So I'm wondering, what are some of the next steps in this research? What would you like to do? What are you going to do? What are you working on?Laura Diaz Yeah, I think, like, I mean, I hope I can spend more time studying the mitochondria. I think, as is true for like, most folks in graduate school, really figuring out, like, where is my niche? Like, where is my lane? Like, I do hope that I get to spend quite a bit more time really deep diving into the mitochondria. Specifically, I'm really curious about what is happening and what other biomarkers are associated with this mitochondrial dysfunction, and also like mitochondrial mutations, which are pretty interesting to think about as well. So I'm kind of following, like what's happening in a molecular mechanism level.Brian Bienkowski Do you like doing research?Laura Diaz Yeah, I love it. Oh, I love it. Even, like and, and when I shouldn't say even, and when I was teaching, like, research was a big part of of my teaching practice with high schoolers. I have, I think this is like something that has been passed on from, from my family, for sure, but in my is just this love for learning and not being afraid of of kind of the unknown. Yeah.Brian Bienkowski So you mentioned earlier this kind of idea of being really interested in kind of professional development, and I know outside of your research, you're also, you're doing some other things, and you've you founded a nonprofit, the Educator Collective for Environmental Justice. So I was wondering if you could just tell us about that organization and why you started it?Laura Diaz Yeah, so when I met Karna Wong who, like, blew my mind about environmental justice and and really started supporting me on my journey through, like, integrating environmental justice in the classroom, I literally started writing curriculum for my class that evening, and I knew that there was a gap in environmental justice curriculum and training for educators at that time, and I was chosen to be a Science Friday educator collaborator, where I was able to actually publish my EJ curriculum, which was really cool. And I started getting invited to give conferences or talks at conferences, and I gave a talk at a climate solutions conference, and that's where I met Samra Pathania, who's also a high school teacher, and he is just as passionate about decarbonization and climate solutions. And so we spent that whole conference just like talking together and visioning together, like how we could create a space for professional development and like, almost like a grassroots movement building for educators around these topics of environmental justice and climate solutions. Because, just like, I have that really, like urgent sense to, like do something now, he's similar with decarbonization. And so originally, we started as a home for Educator professional development for again, EJ and climate solutions. And we actually grew really quickly, which was really cool and supported, started supporting youth. So we had a youth collective, which now we have two Youth Environmental Justice councils that we support. We have a cohort of educators that that we support in EJ and climate solutions and decarbonization. And then we also partner with communities. So we've given workshops to communities like building DIY indoor air filters and giving them like educational workshops around environmental justice. We partnered with promotoras and doing, like, some air pollution monitoring. So it's been this, like, really beautiful little space that that is is growing and thriving.Brian Bienkowski Excellent. And speaking of being too busy to play piano, you also co-founded the Partners for Equity and Research, which supports undergraduates doing community engaged research. So can you also talk about this, maybe a project or two that you've worked on there, and how you work to center community voices and experiences in that initiative?Laura Diaz Yeah, so maybe I could describe a little bit of like, our structure. It's a little bit like, yeah, has some moving pieces, but we are an environmental justice hub that's housed at Sonoma State University, and I co-lead that with Professor Daniel Soto, who's a department chair of Geography, Environment and Planning, and we train undergraduate researchers in community-driven research methods. So I like to think of it as a triangle, the way our partnership works. So we have the university and Dr. Soto's really important. Like, kind of the lead there. He's able to recruit the students at Sonoma State. And then there I, like, I'm another point wearing my nonprofit hat, and then we have our community partners, and they are the North Bay Organizing Project, and the Latinx Student Congress, and our partner there is Manny Morales, and we, with his hope, he recruits students from the Latinx Student Congress, And we have a running Latinx Youth Environmental Justice Council, so they get to come on campus, and Dr. Soto and I train the undergrads to, like, lead these workshops in environmental justice and community health. And it's really amazing. And again, like a lot of the students that we're recruiting, most are Latinx, if not most are first gen and then Dr Soto and I are both Latinx, and we're serving, I think it's 100% Latinx youth EJ council with a Latinx partner. And most of these kids come from a predominantly Latinx frontline EJ community. So it's just like, it's such a beautiful space. And Dr Sota, and I really spent a lot of time thinking about reimagining the academy as a public good, like, how do we make the university a space that actually serves the community? And I think speaking about HSI or Hispanic serving institutions, they are so primed to do that because of who we are, right? And there's a there's trust that's kind of baked in, and just our identity right, apart from, like, our ethics really driving building trust with our partners. And we've been using education as a tool for community deliberation so that we can support these youth as they fight for cleaner air and a more just environment. And so things that we've worked on, and so I think, like that piece of it is, like, more important, almost in like, the stuff that they get to do, because we put in all this work to build this partnership, and now we get to just follow their lead, the youth lead. It's beautiful. And so we've done things like, we've given them air monitors. They get to go out and like, monitor the air and like that data is theirs. And then we teach them the research methods of how to clean that data. So it truly is like a practice of data sovereignty. Like that data is theirs. It does not get pushed out to the cloud. It's on an SD card, and they get to decide what they do with it. And we have a couple other projects, like in the works, but it's been a really like healing practice in some of the environmental justice work I'm privileged to do.Brian Bienkowski Well, I bet some of the participants would agree, and the idea of reimagining the academy to be a public good is what you said. And like that is a pretty simple statement, but it's like pretty radical, if you think about the ways universities and institutions have operated for century, over a century. And it's a pretty radical concept, so good on you for for being part of that change. And does this how beautiful to have you speak about Sonoma State University as being pivotal at one point in your life, and now you are, you are one of those people that's that's providing a space for others. So just that full circle is really cool to hear about.Laura Diaz Yeah, it's been, it's been pretty special.Brian Bienkowski Yeah, for sure. And so you mentioned that you are a mother, so we have had, we actually had a podcast with a couple senior fellows where they discuss being researchers and mothers and how things change them, and it was just one of my favorite podcasts that we've done when I turned the microphone over to them, and I'm wondering just how it has it does has it done the same for you? Has it changed how you've thought about or conducted your research?Laura Diaz Yeah, so I came into grad school already being a mom, and so there are ways that it has impacted how I engage in research, for sure, and I think a really, a really, kind of important component of of the work that we do with at Sonoma State, with P4ER. We're also supporting undergraduate students who are also parents, and creating a space where the student parent feels like their whole self is welcome is incredibly important to some of the things that we do. And so there's like, I often bring my son to our workshops, because I know that if I do, then the students can also bring their kids. And so we're really trying to create an atmosphere where motherhood is welcomed, where it's embraced and it's also encouraged. And I think another like piece of being my son's mom that has really impacted me in research, which I feel like this is, again, I'm like, I love education, but that, I think, is a piece that we don't talk about enough in research, is the role that education or knowledge sharing plays in the process of knowledge production. And so if we do research well, but we don't do teaching well, we aren't pushing the edges of that new knowledge enough. And in research, we get to ask new questions, and we get to present that to new learners who have a different worldview than those of us who are asking those questions, so they can write like during the moment research is being done actually impact that research to be a more like to have a fuller angle to it. And so I just, I think about that a lot, because my son is in third grade and just seeing how he's learning and all that stuff. I think, I think a lot about the role of holistic learning and how that can play a big role in healthy development of of children and and research.Brian Bienkowski And I'm wondering if there are things that you tips you have, or things that you do to decompress, to cope, to make sure that you're doing okay.Laura Diaz I'm a dancer, so I'm a salcera, and I dance with a salsa Maria Dance Company in Oakland. Shout out to my dance family. That is a space where I have to shut my brain off, and it's like you were talking about, like music. I think I've been kind of able to get away with not playing piano for so long, because I've been really intensely dancing and so having, like, an artistic expression for my body has been really important. So like, I that that plays a big role in my own ability to kind of sustain we have work that's justice centered. And the cool thing about that too is that, like, they also really embrace like family. So like, my son will come and and, like, sit and watch practices, which he, like loves doing, which is super cool, because I remember being kid and going to my dad's soccer games and like that being a really like, it actually is, like, a big health promotion piece of my life, right, seeing my parents be active. Um, but anyways, so yeah, dance.Brian Bienkowski I think that's a good point too. Like having your children. See, I'm a big fan. I don't have kids. We are, we are child-free, but I have nieces and nephews, and I think it's so important for kids to see their parents as human beings. Like, yes, mom works hard and does research and but mom also dances like that. I don't know, to me, there's something cool about kids seeing their parents as whole human beings. So Laura, before we get to some of the fun questions and get you out of here, what are you optimistic about?Laura Diaz this summer, we came off of doing a summer institute for educators, and being able to be in community with educators who are these incredible like, they're the heart of a lot of of their community, like, of their school communities, and the impact that they have on on the kids that they get to teach, like, really does provide a lot of hope for me. And I think, like also being able to partner with youth and seeing just how they're such a raw reflection of society, how they're like, not fully yet assimilated into our social hierarchies. And when they see something that's wrong, like, they call it outright then and there, right? And they're like, dude, let's do something about it. And like, that is the energy that we need in this space, and it's such a privilege to work in partnership to their own EJ activism.Brian Bienkowski Awesome. Well, what a beautiful note to end on. So I have three rapid fire questions where you can just answer with one word or a phrase. My dream vacation isLaura Diaz Mexico City.Brian Bienkowski I feel most creative when I'mLaura Diaz Dancing salsaBrian Bienkowski if I could have dinner with one person, it would beLaura Diaz Leslie Jones.Brian Bienkowski Tell me about Leslie Jones?Laura Diaz Oh, she's someone I really look up to. She also has a brother who struggled and like seeing the way her autobiography. Is amazing, by the way, but just like the way that she's chosen to like, be strong and push through that and also be authentic and be raw and be herself, is something that I like. I hope that I bring in all the spaces that I have the privilege to navigate through.Brian Bienkowski Well, you've certainly brought it to the space today. And I don't know if it's if it's her autobiography or not, but what is the last book you read for fun?Laura Diaz I read In the Dream House, which is also an autobiography by Carmen Maria Machado. It's really beautiful. I read a lot. So I also read hood. Just finished reading Hood Feminism, which is an amazing book by Mickey Kendall, and it like talks about how feminism needs to prioritize the hood bipoc woman's experience. It's amazing.Brian Bienkowski But Laura, it has been so wonderful to have you on today. I'm so glad you're in this program and to be introduced to your work and your mind and the things that you're thinking about. So thank you so much.Laura Diaz Yeah, thank you so much.

Laura Diaz joins the Agents of Change in Environmental Justice podcast to discuss the intersection of social and environmental stressors on children’s health.Diaz, a current fellow and a Ph.D. student in Environmental Health Sciences at UC Berkeley, also talks about how her own childhood shaped her understanding of environmental injustice, and how being a mother has shaped her research – and her life.The Agents of Change in Environmental Justice podcast is a biweekly podcast featuring the stories and big ideas from past and present fellows, as well as others in the field. You can see all of the past episodes here.Listen below to our discussion with Diaz and subscribe to the podcast at iTunes or Spotify. Agents of Change in Environmental Justice · Laura Diaz on how social and environmental stress impact children’s healthTranscriptBrian BienkowskiLaura, how are you doing today?Laura Diaz I'm doing okay. How are youBrian Bienkowski I'm doing great. And where are you today?Laura Diaz I am in South San Francisco, which is close to the San Francisco International Airport.Brian Bienkowski Very cool. I love it out there. And you are from originally not far from there. So tell me a little bit about growing up in Northern California.Laura Diaz Yeah, so I grew up in the East San Francisco Bay Area, and specifically, it's like the geographic location where the watershed from the Sierra mountains meets the mouth of the San Francisco Bay, and it's beautiful. And just behind where the Bay is, there's these rolling golden hills. And because of the history that Pittsburgh has, which is my hometown, with the fossil fuel industry, and specifically during the Gold Rush, they were actually mining coal out there that laid the foundation for a polluting industry which persists today, and it's become one of the more affordable places in the San Francisco Bay area to live. And so I lived in between this corridor of polluting industry, right along that water, which included the Dow Chemical Plant, the power plant and several other toxic release facilities. And then on the other side of us was a highly trafficked freeway. And then we lived there until it was about four and then shortly after, we moved just over that same freeway, and the freeway was like legit our neighbors and the that whole corridor polluting industry was still an eye shot of where we lived. And those cities are largely known as commuter cities because they're so affordable. A lot of families move out there to raise their family, and that was true for my parents as well. So they commuted about an hour and a half, and so a lot of our childhood was spent largely unsupervised, and at some point, my parents decided to get us an inter-district transfer to the city where they worked. And so they worked in a city called wanna Creek, California, and that city is predominantly white and home to the uber rich. And I remember like, being at school and just feeling like I really didn't, like fit in. And it went beyond that, like kind of normal, like what I see with my son, where he's, like, trying to make friends and stuff. It went beyond that, like something just didn't fit. And I remember like, walking home from school, and I would have to walk through this outdoor plaza with stores like Neiman Marcus and Tiffany's and make my way to my dad's tailoring shop. And like, I remember opening the door, and I would get this like sense of relief, and I would feel like I could breathe again. And it was like home, and yet, I would see my dad on his hands and knees fixing the clothing of my classmates parents. And then every day we would take our trek back home. So we'd be going from this very affluent space, it was very green, a lot of open space back home, to this space where it's a lot of concrete, like again, we'd see, like, that whole polluting industry, and yet, like, I'd hop out of the car super excited, run to my neighbor's house and we'd be playing basketball for the rest of the evening. I have, like, so much love for where I grew up, and I feel like my work now is like. Of letter to my community, and I had this like daily reminder of the difference between wealth and poverty, between predominantly white communities and predominantly diverse communities.Brian Bienkowski Well, that's a really beautiful way to paint your hometown. I have to say, when I first looked it up, I was like, I did not know Laura was from Pittsburgh. When I met her, she seemed like she was from the West Coast, so I did not know that there was a Pittsburgh California. But thank you so much for painting that picture. And you, you know, you've mentioned this kind of industrial backdrop and maybe some social dynamics and racial dynamics at school that were uncomfortable. I'm wondering where along the way you became aware or interested in kind of the concept of environmental justice and injustice?Laura Diaz Yeah. So, I mean, like those, like, big smokes stacks, like, what we see in pictures a lot when we see, like, read articles about environmental justice, like, that was the backdrop to my childhood. And yet, I had no idea that that, that I grew up in an environmental justice community, right? So I am a former high school science and math teacher, and there was a summer where I did a professional development program in the topic of sustainability. It had it was there that I met Karna Wong, and she's a faculty at Sonoma State University, and she absolutely changed my life. She gave a workshop on environmental justice, and she taught us about the principles of environmental justice, various frameworks of EJ and her and I, like, hit it off like it was, it was great. This is why I love, like, professional development programs, which we can talk about later. But she also showed me this database called CalEnviroScreen, and that is, it's basically a map of California, and it displays community exposures to pollution, health burdens and demographic characteristics. And that was the first time that I saw my community in bright red, because bright red means more burdens. And then I saw Walnut Creek bright green, and bright green is associated with less burdens, or under-burden. And it just was like this final puzzle piece of like, like, whoa, everything came together. And I like, understood that that feeling of like something wasn't right made so much sense by looking at that map, and I realized that environmental justice wasn't only something I like, loved learning about, it also impacted my life. I don't know, and I'm never going to know, if growing up in close proximity to these facilities is a reason why I have two chronic autoimmune diseases, but it does drive my work. And I think also, in addition to that, there was another educator fellowship that I was on, and I did that with Earthwatch. We were out at catalea Island, and we were studying Harmful Algal Blooms. And while we were out there, my mom called me, and she was like, I made it out, but paradise is on fire. And that was in 2018 and although she made it out alive, 85 folks did not, and that was the campfire. And over 13,000 homes were lost in one of those of my mom's and it's like, it's hard to talk about this, but it's like, because it's so deeply personal, right? But I remember flying home from that experience and waiting outside of the airport and it was raining ash, and those ashes included my mom's home. So it's just the impacts of climate justice, and environmental justice has hit me, personally, very hard, and I think more recently, I've been really thinking about the connection between wildfires in California, the fossil fuel industry and our inability to transition away fast enough, and how my community is going to continue to pay the price until we do so. And that really drives the work that I do. And like you can hear my voice shaking, but it's like I have so much passion to you, and it's so important. There's, there's an urgency to this work that's needed that I'm I'm not quite sensing enough in the academic spheres that I'm in now, but I hope to be a part of that driving force.Brian Bienkowski And I've been asking everybody this question before we get into some of your your research and your education, what is a moment or event that has helped shape your identity?Laura Diaz Yeah, okay, I think there's a couple I feel like we're getting into, like, the intense stuff in the beginning. So like, Sorry my voice is shaking, but also self-deprecating humor is how I get. So, I think the first thing that really, really impacted like who I am and how I moved through this world, was when I was in ninth grade, my dad and I had to go to the county courthouse, and it was the first time that I saw my brother handcuffed. And we were there to see him and be there for him while he was going to be sentenced for his first felony. And I remember the judge asked his family to stand up those, those of us who were there in support. And I was bawling as my I was seeing my hero like out there behind a glass wall in handcuffs, and I was like, barely could stand up, and I was just tears were just rolling down my face, and, like, for the longest time, I thought it was actually my fault that he got sentenced, because I couldn't keep it together, right? It was just I was I must have been around 13, right? a kid. And I think during my adolescence, I really developed this, like, strong understanding of the impact of oppression on the lives of children, and it really is the root of how I move through the work that I do. And I think also kind of on a more tender side, a moment that really has shaped who I am, is being my son's mom, and the day I became his mom was the most beautiful day of my life. And I tell him often how lucky I am to be his mom, and I like to say that my most proudest title is being soccer mom. And I do know too that like the most important thing I can do, personally and professionally is invest in my son and my family.Brian Bienkowski Awesome. Well, thank you so much for both of those very we will get you away from these, all of these that are pulling at your emotions. Maybe we'll circle back and we'll get emotional again, but thank you so much for opening up about that. I'm sure there are others who can relate. And when you talk about tears streaming down, I was hoping my my blue light glasses were hiding we're hiding mine on that so, so let's change gears a little bit. And you went to so you mentioned Sonoma State University, which is now recognized as a Hispanic serving institution, and you went there for your undergraduate degree. So we've had folks on talking about going to historically Black colleges and kind of the impact that had on them and a level of comfort and that it brought them. So I was wondering if you could talk about that experience and how going to a Hispanic Serving Institution benefited you?Laura Diaz Yeah, I, I remember the first week being on campus and like, being overwhelmed with this, like, sense of hope. And I think, and it was great, like I felt like, you're saying, I just felt like safe, that that uncomfortable, like unwelcoming feeling that I felt when I was going to schools in Walnut Creek was like gone. And I knew that I was believed in and supported by by the faculty. The commitment to teaching excellence at HSIs is so high, and that's really impacted my teaching philosophy now, and I understand firsthand what it means like to create a vulnerable learning environment and what it means to like not be in one, right? And because I was able to really thrive in this space, I majored in Molecular Cell bio. I double minored in Chem and in music. I was part of the chamber music orchestra, like I was, like, loving life. It was great. And also, my junior year, it started getting sick, and I was having to walk to school with a cane, and I ended up getting diagnosed with lupus, and during that diagnosis period that was really difficult. And despite that, I knew that the faculty were there for me. I knew my classmates were there for me, and they really helped me push through a really, really difficult time for me. And so I just, I feel very committed to what education means, what that means for social mobility, and that's stayed with me. And continue, I continue to work and partner with Sonoma State, which is, yeah, really great.Brian Bienkowski Yeah, what a great opportunity. Do you still play music?Laura Diaz I don't, but I need to. I played the piano. Oh,Brian Bienkowski no, no, that's that was my next question. That's very cool. Yeah, I am a musician. I play a whole variety of instruments. And I've said on the podcast before that it just it feels like it is that other side of the brain. It just feels so good to take some time to stretch the create creative legs every now and then, after staring at a computer for so long. So I'm always curious.Laura Diaz Yeah, I hear that, and hopefully this inspires me to, like, get it together,Brian Bienkowski get back to it. Yeah. Well, I'm sure you have as we're gonna get into it sounds like we have plenty going on, but I hope you find some time. So now you are studying air pollution, specifically particulate matter burdes in marginalized communities. So particulate matter is linked to negative health outcomes, and one of them that you focus on is mitochondrial dysfunction. So can you explain first, what mitochondria are and how air pollution may affect them?Laura Diaz So mitochondria are these fascinating little organelles that I've been spending several years thinking about. They're the site of chemical energy production of our cells, so they make the energy that our cells need in order to actually function properly. And they're really unique. So they have their own DNA or their own genome, and in that, within that, it codes for 13 proteins which are vital for the mitochondria to be functioning properly. And what's interesting about that is that they they lack these protective mechanisms that, like our nuclear DNA has, and so it makes them particularly vulnerable to situations where our cells are undergoing stress, and we see that mitochondrial function declines with aging and also with disease. And what I spend a lot of time thinking about is what mitochondrial function or dysfunction looks like in epithelial cells. And those are the cell types that we find in the lining of our mouth. They're in our lungs, and there's like outer barrier of our skin, so they come in contact with this, like wild outer world, and play this really important protective mechanism, and they they play a big role in detoxification. And so what happens when they're exposed to particulate matter? There's actually an increase in free radicals in our in the cell, and those are called reactive oxygen species, and those, if there's too many and there's an imbalance, those can cause mitochondrial dysfunction, and that's what I'm spending a lot of time thinking about.Brian Bienkowski So if these mitochondria are disrupted in some way by and I should say particulate matter is fine particulate pollution. This can come from anything from wildfires to traffic to to heavy industry, fossil fuel burning, if the mitochondria are disrupted, what kind of impact may that have on, let's say, developing children?Laura Diaz Yeah, so I, my research focuses on child health, and again, I'm really thinking about these epithelial cells and what's happening in relation to the exposure of, like, what you're saying with particulate matter and and when we see that mitochondrial dysfunction, it actually triggers a cascade of events to happen in the cell. So the cell tries to fix these problems when they come up, but when it's constantly having to fix these problems, that's when, that's when, like, long-term issues can can arise. And so what we see is that the this outer lining of cells can be really impacted by mitochondrial dysfunction, because they they get put in this like pro-inflammatory state, and so then they become really vulnerable to things like allergens. So what I'm studying, then, is, is that mitochondrial dysfunction playing a role in the development of diseases like eczema or rhinitis or asthma among children in frontline environmental justice communities.Brian Bienkowski So as part of this, you're also looking at adverse childhood experience known as ACES, which was a new acronym for me after I met you at the retreat. That was something I didn't know about. So in addition to the air pollution and mitochondrial dysfunction, you're looking at aces. So can you explain aces and why you feel it's an important part of including in this research,Laura Diaz ACES stands for Adverse Childhood eEperiences. In California, there's a lot of work being done on the public health end of things, and it's getting labeled as toxic stress. What it is is it's a survey with 10 questions that assesses a child's exposure to abuse, neglect and household challenges. And back in the 90s, there was a groundbreaking study that was done, and they found that exposure to ACES was associated with increased risk of death from seven out of 10 of the leading causes of death and so and there's been a lot more work done now, but I really want to invite us all in, like environmental health work and environmental justice, to be thinking about day to day stress, and that exposure to stress as an environmental exposure, just like we would think about particulate matter. And in order to understand the impact of oppression and the health impacts living in frontline communities, I think it's really important that we also include exposure to stress. And what I've found in my research is that exposure to ACES is associated with an increase in mitochondrial dysfunction and so, and I'm seeing that among a cohort of children, right? So it like the changes that becomes embodied in our cells happens pretty quickly. It can at least.Brian Bienkowski So you're seeing that not only. So if there are these environmental insults, and then you pile on kind of just day to day stress in a child's life, whether that's from inside or outside of the home, the combination of those, they're both doing bad things at the cellular level, to the kid or to a child, and setting them up for potential increased illness.Laura Diaz Yeah, and I think, like, I'm really thinking about the mitochondria a lot, obviously, but if we think about being in a state of stress, where we're in this, like fight or flight, like our physiological response, our cells have an increased need of energy, and when that happens over and over and over again, then the mitochondria is being overworked. And so understanding what's happening at the cellular level is also really important.Brian Bienkowski v really fascinating research. And I love the idea of thinking more about stress, and of course, with your research with kids, but even for adults. I mean, I think stress is such a kind of a silent killer. I mean, it just, it's so bad for our body, and yet, a lot of us kind of live with it, and it's part of our, part of our life, so it's really important to to remember that. So I'm wondering, what are some of the next steps in this research? What would you like to do? What are you going to do? What are you working on?Laura Diaz Yeah, I think, like, I mean, I hope I can spend more time studying the mitochondria. I think, as is true for like, most folks in graduate school, really figuring out, like, where is my niche? Like, where is my lane? Like, I do hope that I get to spend quite a bit more time really deep diving into the mitochondria. Specifically, I'm really curious about what is happening and what other biomarkers are associated with this mitochondrial dysfunction, and also like mitochondrial mutations, which are pretty interesting to think about as well. So I'm kind of following, like what's happening in a molecular mechanism level.Brian Bienkowski Do you like doing research?Laura Diaz Yeah, I love it. Oh, I love it. Even, like and, and when I shouldn't say even, and when I was teaching, like, research was a big part of of my teaching practice with high schoolers. I have, I think this is like something that has been passed on from, from my family, for sure, but in my is just this love for learning and not being afraid of of kind of the unknown. Yeah.Brian Bienkowski So you mentioned earlier this kind of idea of being really interested in kind of professional development, and I know outside of your research, you're also, you're doing some other things, and you've you founded a nonprofit, the Educator Collective for Environmental Justice. So I was wondering if you could just tell us about that organization and why you started it?Laura Diaz Yeah, so when I met Karna Wong who, like, blew my mind about environmental justice and and really started supporting me on my journey through, like, integrating environmental justice in the classroom, I literally started writing curriculum for my class that evening, and I knew that there was a gap in environmental justice curriculum and training for educators at that time, and I was chosen to be a Science Friday educator collaborator, where I was able to actually publish my EJ curriculum, which was really cool. And I started getting invited to give conferences or talks at conferences, and I gave a talk at a climate solutions conference, and that's where I met Samra Pathania, who's also a high school teacher, and he is just as passionate about decarbonization and climate solutions. And so we spent that whole conference just like talking together and visioning together, like how we could create a space for professional development and like, almost like a grassroots movement building for educators around these topics of environmental justice and climate solutions. Because, just like, I have that really, like urgent sense to, like do something now, he's similar with decarbonization. And so originally, we started as a home for Educator professional development for again, EJ and climate solutions. And we actually grew really quickly, which was really cool and supported, started supporting youth. So we had a youth collective, which now we have two Youth Environmental Justice councils that we support. We have a cohort of educators that that we support in EJ and climate solutions and decarbonization. And then we also partner with communities. So we've given workshops to communities like building DIY indoor air filters and giving them like educational workshops around environmental justice. We partnered with promotoras and doing, like, some air pollution monitoring. So it's been this, like, really beautiful little space that that is is growing and thriving.Brian Bienkowski Excellent. And speaking of being too busy to play piano, you also co-founded the Partners for Equity and Research, which supports undergraduates doing community engaged research. So can you also talk about this, maybe a project or two that you've worked on there, and how you work to center community voices and experiences in that initiative?Laura Diaz Yeah, so maybe I could describe a little bit of like, our structure. It's a little bit like, yeah, has some moving pieces, but we are an environmental justice hub that's housed at Sonoma State University, and I co-lead that with Professor Daniel Soto, who's a department chair of Geography, Environment and Planning, and we train undergraduate researchers in community-driven research methods. So I like to think of it as a triangle, the way our partnership works. So we have the university and Dr. Soto's really important. Like, kind of the lead there. He's able to recruit the students at Sonoma State. And then there I, like, I'm another point wearing my nonprofit hat, and then we have our community partners, and they are the North Bay Organizing Project, and the Latinx Student Congress, and our partner there is Manny Morales, and we, with his hope, he recruits students from the Latinx Student Congress, And we have a running Latinx Youth Environmental Justice Council, so they get to come on campus, and Dr. Soto and I train the undergrads to, like, lead these workshops in environmental justice and community health. And it's really amazing. And again, like a lot of the students that we're recruiting, most are Latinx, if not most are first gen and then Dr Soto and I are both Latinx, and we're serving, I think it's 100% Latinx youth EJ council with a Latinx partner. And most of these kids come from a predominantly Latinx frontline EJ community. So it's just like, it's such a beautiful space. And Dr Sota, and I really spent a lot of time thinking about reimagining the academy as a public good, like, how do we make the university a space that actually serves the community? And I think speaking about HSI or Hispanic serving institutions, they are so primed to do that because of who we are, right? And there's a there's trust that's kind of baked in, and just our identity right, apart from, like, our ethics really driving building trust with our partners. And we've been using education as a tool for community deliberation so that we can support these youth as they fight for cleaner air and a more just environment. And so things that we've worked on, and so I think, like that piece of it is, like, more important, almost in like, the stuff that they get to do, because we put in all this work to build this partnership, and now we get to just follow their lead, the youth lead. It's beautiful. And so we've done things like, we've given them air monitors. They get to go out and like, monitor the air and like that data is theirs. And then we teach them the research methods of how to clean that data. So it truly is like a practice of data sovereignty. Like that data is theirs. It does not get pushed out to the cloud. It's on an SD card, and they get to decide what they do with it. And we have a couple other projects, like in the works, but it's been a really like healing practice in some of the environmental justice work I'm privileged to do.Brian Bienkowski Well, I bet some of the participants would agree, and the idea of reimagining the academy to be a public good is what you said. And like that is a pretty simple statement, but it's like pretty radical, if you think about the ways universities and institutions have operated for century, over a century. And it's a pretty radical concept, so good on you for for being part of that change. And does this how beautiful to have you speak about Sonoma State University as being pivotal at one point in your life, and now you are, you are one of those people that's that's providing a space for others. So just that full circle is really cool to hear about.Laura Diaz Yeah, it's been, it's been pretty special.Brian Bienkowski Yeah, for sure. And so you mentioned that you are a mother, so we have had, we actually had a podcast with a couple senior fellows where they discuss being researchers and mothers and how things change them, and it was just one of my favorite podcasts that we've done when I turned the microphone over to them, and I'm wondering just how it has it does has it done the same for you? Has it changed how you've thought about or conducted your research?Laura Diaz Yeah, so I came into grad school already being a mom, and so there are ways that it has impacted how I engage in research, for sure, and I think a really, a really, kind of important component of of the work that we do with at Sonoma State, with P4ER. We're also supporting undergraduate students who are also parents, and creating a space where the student parent feels like their whole self is welcome is incredibly important to some of the things that we do. And so there's like, I often bring my son to our workshops, because I know that if I do, then the students can also bring their kids. And so we're really trying to create an atmosphere where motherhood is welcomed, where it's embraced and it's also encouraged. And I think another like piece of being my son's mom that has really impacted me in research, which I feel like this is, again, I'm like, I love education, but that, I think, is a piece that we don't talk about enough in research, is the role that education or knowledge sharing plays in the process of knowledge production. And so if we do research well, but we don't do teaching well, we aren't pushing the edges of that new knowledge enough. And in research, we get to ask new questions, and we get to present that to new learners who have a different worldview than those of us who are asking those questions, so they can write like during the moment research is being done actually impact that research to be a more like to have a fuller angle to it. And so I just, I think about that a lot, because my son is in third grade and just seeing how he's learning and all that stuff. I think, I think a lot about the role of holistic learning and how that can play a big role in healthy development of of children and and research.Brian Bienkowski And I'm wondering if there are things that you tips you have, or things that you do to decompress, to cope, to make sure that you're doing okay.Laura Diaz I'm a dancer, so I'm a salcera, and I dance with a salsa Maria Dance Company in Oakland. Shout out to my dance family. That is a space where I have to shut my brain off, and it's like you were talking about, like music. I think I've been kind of able to get away with not playing piano for so long, because I've been really intensely dancing and so having, like, an artistic expression for my body has been really important. So like, I that that plays a big role in my own ability to kind of sustain we have work that's justice centered. And the cool thing about that too is that, like, they also really embrace like family. So like, my son will come and and, like, sit and watch practices, which he, like loves doing, which is super cool, because I remember being kid and going to my dad's soccer games and like that being a really like, it actually is, like, a big health promotion piece of my life, right, seeing my parents be active. Um, but anyways, so yeah, dance.Brian Bienkowski I think that's a good point too. Like having your children. See, I'm a big fan. I don't have kids. We are, we are child-free, but I have nieces and nephews, and I think it's so important for kids to see their parents as human beings. Like, yes, mom works hard and does research and but mom also dances like that. I don't know, to me, there's something cool about kids seeing their parents as whole human beings. So Laura, before we get to some of the fun questions and get you out of here, what are you optimistic about?Laura Diaz this summer, we came off of doing a summer institute for educators, and being able to be in community with educators who are these incredible like, they're the heart of a lot of of their community, like, of their school communities, and the impact that they have on on the kids that they get to teach, like, really does provide a lot of hope for me. And I think, like also being able to partner with youth and seeing just how they're such a raw reflection of society, how they're like, not fully yet assimilated into our social hierarchies. And when they see something that's wrong, like, they call it outright then and there, right? And they're like, dude, let's do something about it. And like, that is the energy that we need in this space, and it's such a privilege to work in partnership to their own EJ activism.Brian Bienkowski Awesome. Well, what a beautiful note to end on. So I have three rapid fire questions where you can just answer with one word or a phrase. My dream vacation isLaura Diaz Mexico City.Brian Bienkowski I feel most creative when I'mLaura Diaz Dancing salsaBrian Bienkowski if I could have dinner with one person, it would beLaura Diaz Leslie Jones.Brian Bienkowski Tell me about Leslie Jones?Laura Diaz Oh, she's someone I really look up to. She also has a brother who struggled and like seeing the way her autobiography. Is amazing, by the way, but just like the way that she's chosen to like, be strong and push through that and also be authentic and be raw and be herself, is something that I like. I hope that I bring in all the spaces that I have the privilege to navigate through.Brian Bienkowski Well, you've certainly brought it to the space today. And I don't know if it's if it's her autobiography or not, but what is the last book you read for fun?Laura Diaz I read In the Dream House, which is also an autobiography by Carmen Maria Machado. It's really beautiful. I read a lot. So I also read hood. Just finished reading Hood Feminism, which is an amazing book by Mickey Kendall, and it like talks about how feminism needs to prioritize the hood bipoc woman's experience. It's amazing.Brian Bienkowski But Laura, it has been so wonderful to have you on today. I'm so glad you're in this program and to be introduced to your work and your mind and the things that you're thinking about. So thank you so much.Laura Diaz Yeah, thank you so much.

Iowa Farmers Are Restoring Tiny Prairies for Sustainability Boons

Farmers in the heartland are restoring swaths of the prairie with government help. The aim is to reduce nutrient runoff from cropland, and help birds and bees.

The little tracts of wilderness grow on Maple Edge Farm in southwest Iowa, where the Bakehouse family cultivates 700 acres of corn, soybeans and alfalfa. Set against uniform rows of cropland, the scraps of land look like tiny Edens, colorful and frowzy. Purple bergamot and yellow coneflowers sway alongside big bluestem and other grasses, alive with birdsong and bees.The Bakehouses planted the strips of wild land after floodwaters reduced many fields to moonscapes three years ago, prompting the family to embark on a once-unthinkable path.They took nearly 11 acres of their fields out of crop production, fragments of farmland that ran alongside fields and in gullies. Instead of crops, they sowed native flowering plants and grasses, all species that once filled the prairie.The restored swaths of land are called prairie strips, and they are part of a growing movement to reduce the environmental harms of farming and help draw down greenhouse gas emissions, while giving fauna a much-needed boost and helping to restore the land.As the little wildernesses grew, more and more meadowlarks, dickcissels, pheasants and quail showed up, along with beneficial insects. Underground, root networks formed to quietly perform heroic feats, filtering dangerous nutrient runoff from crops, keeping soil in place and bringing new health to the land.“We’re thinking about our farm as a small piece of the overall good puzzle,” said Jon Bakehouse, on a visit to the family’s fields one sunny morning earlier this summer. “On a larger scale, we’re all in this together.”Subscribe to The Times to read as many articles as you like.

Nearsightedness Has Become a Global Health Issue

Myopia is projected to affect half of the world’s population by 2050. A new report says it needs to be countered by classifying it as a disease and upping children’s outdoor time

In 350 B.C.E. Aristotle noted that some people went about their days with what he called “short sight.” People with this condition, he found, would habitually narrow their eyelids to focus their vision—an observation widely credited as the first attempt at defining nearsightedness, or myopia. More than two millennia later, health officials are paying new attention to this old condition for a startling reason: myopia has reached epidemic levels worldwide.Myopia’s prevalence has dramatically increased in recent decades, now affecting as much as 88 percent of the population in some Asian countries. Although it seems most acute in Asian cities, myopia’s growing prevalence is by no means an exclusively regional trend. By 2050, according to one estimate, five billion people—half the world’s population—will be nearsighted. The U.S., which has been less diligent than some other countries in tracking myopia cases, saw a jump in prevalence from 25 percent of people aged 12 to 54 in the early 1970s to 42 percent in the early 2000s, according to the last major national survey of the condition.These statistics matter because myopia is a leading cause of visual impairment, and it can precipitate serious diagnoses that range from detached retinas to glaucoma.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.A search is now underway for tangible measures to stem this rising tide. An expert panel from the National Academies of Sciences, Engineering and Medicine (NASEM) released a report in September entitled Myopia: Causes, Prevention, and Treatment of an Increasingly Common Disease. It lays out a series of recommendations, one of which calls for the Centers for Medicare & Medicaid Services to reclassify myopia as a disease that necessitates a medical diagnosis—a step that would encourage federal and state agencies, along with professional associations, to devote resources to reversing the situation. Notably, the committee also recommended that children spend one to two hours outdoors each day.Terri L. Young, co-chair of the NASEM committee that produced the report and chair of the department of ophthalmology and visual sciences at the University of Wisconsin–Madison, talked with Scientific American about the implications of the myopia epidemic for people with myopia and policymakers.[An edited transcript of the interview follows.]I’d like to begin with the most basic of basics. Could you define what myopia, or nearsightedness, is?I’ll start off with what a person with myopia experiences. Myopia is a condition in which an individual sees an object up close clearly but cannot see it clearly at a distance without optical correction. They have natural blurred vision at a distance.Optically, there is a detailed definition that involves the very basics of how we see. Scattered light rays that enter the eye pass through multiple ocular components that reduce the scatter to focus the rays onto the retina, which converts the light into an electrical signal that is transferred through the optic nerve. The optic nerve is similar to a telephone cable that connects the eye to the occipital cortex at the very back of the brain, where what is viewed is then processed and interpreted.The focus of those wavelengths that enter the eye and travel through all its optical components needs to coincide on the retina. In the case of nearsightedness, or myopia, the focus of the light occurs in front of the retina.Myopia seems to be getting more attention lately, both in the U.S. and internationally. Why is that?Myopia prevalence rates are at epidemic levels, especially in urban Asian communities, where in recent times upward of 80 to 90 percent of young individuals have developed myopia. There are large, government-sponsored myopia research institutes in many parts of Asia, including Taiwan, Singapore, China, Hong Kong and Japan.Take Singapore, for example. All young men there are required to perform [two years] of military service after completing high school. Many of these military conscripts, and in particular the ones who are being prepared to go into battle or fly fighter planes, often need glasses or other corrective means for their myopia to fulfill those functions, causing concern for national security.And what about in the U.S.?It’s now certainly an issue in the U.S. as well. Research on myopia is conducted primarily in ophthalmologic and optometric training and research academic programs. But it hasn’t garnered, for whatever reasons, the same sense of urgency and funding as is the case for other parts of the world.In the U.S., we don’t have good prevalence data for myopia and other refractive errors, such as astigmatism and hyperopia [farsightedness]. Health care in this country is so varied in terms of everything from access to dissemination of vision care; because we don’t have a nationalized health system, we also don’t have a national database to provide standardized tracking and reporting.Aren’t there already simple ways to deal with myopia, such as getting a new prescription for glasses? Why is it perceived as becoming a global health problem?Myopia correction is not just an inconvenience of glasses or contact lenses. It predisposes a person to other eye conditions that can lead to blindness. Higher degrees of myopia are associated with eye conditions: premature cataracts, glaucoma, retinal tears and detachments and myopic macular degeneration.What’s happened in Asian communities is that the baseline level of refraction, the deflection of wavelengths as they pass through the eye, is trending toward nearsightedness. This shift is reflected in more individuals with high-grade myopia, with its increased ocular risks, as I described earlier. So instead of that group reflecting 3 to 5 percent of myopic individuals, it’s risen to 10 percent or more.Access to quality vision care, with proper and standardized dissemination for all children, is a major issue in [the U.S.] There are many children who don’t have steady access to care and the opportunity for continued changes in spectacle correction as they grow. If they can’t see, they can’t learn. If they don’t learn, they may get discouraged. If they get discouraged, they tend to act out or to not perform well in school—which has lifelong educational, vocational and economic impacts.Is there some idea why this myopia epidemic is happening?Nowadays, children are indoors more often, and they’re not getting as much outdoor play. Outdoor light enables the visual system to process a variety of spectral wavelengths of light for a certain duration of time, and that affects normal eye development and growth. Our report reaffirms what has been in the scientific literature for more than 15 years: increased childhood outdoor time appears to be protective for myopia onset and development.In urban Asia, education is highly regarded, and children undergo indoor schooling for relatively more hours per day—routinely with additional tutorial sessions on evenings and weekends. In Singapore, for example, there are fewer green spaces, and living situations are generally more vertical because of limited land mass. There are fewer nonclassroom hours and places for children to go outside to view the horizon for extended periods of time. That’s becoming more of the case in the urban U.S. as well.What does being outside do to promote healthy eyes?There are different and varied light wavelengths that enter the eye from outdoor versus indoor exposures. And there are differences in luminance—higher-intensity versus lower-intensity light levels. In the report, there is a lengthy discussion on what is called the “visual diet”—the environmental factors affecting the myopic eye—and there is a consensus that more research is needed.What about the role of electronic devices in promoting myopia?That’s certainly a trend that has exponentially grown in activity and use in our younger generations. I am a pediatric ophthalmologist. I see two- or three-year old children in my clinic who are comfortably playing with cell phones. This close-up activity is generally indoors. The limited research findings regarding electronic device impact on myopia development are inconclusive, however. Reflected in our report, studies could not support unequivocal evidence that using digital devices, especially electronic small devices, is an influencer for this shift toward myopia.What measures have countries implemented to try preventing or correcting myopia in young people?The Singapore Ministry of Health instituted outdoor playtime or recess during school hours. There are now programs in China and in Taiwan where classroom settings have been altered with the use of glass walls or colored light bulb use to increase outdoor daylight exposure. Children are undergoing treatment with atropine eye drops, which in some reports diminishes the shift toward myopia over time in the school-age years. The effect of the drops is not curative, however, and there are concerns regarding unknown long-term effects because we don’t quite understand the specific biochemical actions of atropine. Diagnosed children are also prescribed multifocal contact lenses or eyeglasses [progressive lenses that have different prescription zones to correct vision at different distances].One of the main findings of the report that you co-chaired is the recommendation that myopia be classified as a disease. Can you explain why the consensus of the panel felt that was important?The issue needs escalation to a recognized disease category to underscore its short- and long-term visual health consequences, and to attract attention and funding dollars on multiple and varied fronts for effective screening, treatment, prevention and research study.It takes a multipronged team to elevate this issue. That groundswell would have to come from parents, educators and educator societies, local to national health care systems, local to national policymakers, public health experts, researchers, funding agencies, insurance companies, etcetera. All [of these groups] need to recognize that continuous vision screening starting in early childhood is important. In addition to implementation, the data from those screening visits need to be collated for national database entry for improved monitoring in this country.What do you think should be the main takeaway from this report?In this country, if we elevate this condition to be considered a disease and recognize its impact on our children and ultimately on our future workforce, that would be monumental.

Riding Bikes with the Dutch

Michael Bauch, a Long Beach resident and independent filmmaker, noticed that many of his local errands involved short rides which were less than three miles. In the summer of 2007 he and his family went to Amsterdam, to document the biking and walking culture that is so natural to the Dutch people. The film suggests that we in the U.S. re-examine our view of bicycles.

The Connection Between Bats and Coronavirus: Wildlife is not to blame

What exactly is the connection between bats and coronavirus? And how has sheltering-in-place disrupted field research in California and beyond? State and local governments have set restrictions on bat research and rescue in an effort to curtail the spread of the coronavirus. Dr. Winifred Frick, chief scientist of Bat Conservation International, describes how the new restrictions have affected conservation efforts.

Sprayed

An exploration of what happens when whole communities get exposed to toxins: Naled sprayed on Miami residents to fight Zika virus, Agent Orange sprayed on the Vietcong, and release of GMO mosquitoes in Brazil with pyriproxyfen added to drinking water to fight dengue. What are the results for nature and humanity? We meet Agent Orange survivors at Vietnamese detoxification and rehabilitation centers, parents of babies born with microcephaly from Zika virus, and Florida residents dealing with efforts to kill mosquitoes carrying Zika virus. Perspectives of doctors, scientists, and politicians are balanced with voices of ordinary citizens and victims to explore concerns about the potential impact on current and future generations.
