Egg labels, egg-splained: from cage-free to free-range, how to eat ethically and economically

News Feed
Friday, April 26, 2024

Shopping for eggs at the grocery store can be a confusing experience. Cartons are labeled with all kinds of descriptors – natural, organic, cage-free, free-range – and some cost more at checkout. But what do they actually mean, and for ethically minded consumers, are they actually worth the money?Protein-packed eggs are linked to relatively low carbon emissions compared with other land-based animal protein sources, but not all eggs are created equal when it comes to the environment, health or animal welfare, experts say.“When it comes to ensuring better lives for laying hens, consumers have a lot of power, as long as they’re not led astray by meaningless labels,” said Daisy Freund, vice-president of farm animal welfare at the American Society for the Prevention of Cruelty to Animals, or ASPCA.The Guardian spoke with several experts, who explained what these egg labels mean, and how to shop in a way that balances a concern for hens with what’s good for the planet and your own wallet.What exactly do different egg labels mean?Grade AA, A or BGrade AA eggs are considered the best, and have ‘thick and firm’ whites. Illustration: Olivia de Salve Villedieu/The GuardianConsumer grades rate the interior quality of the egg yolk and white, as well as the appearance and condition of the shell. Grade AA eggs are considered the best, and have “thick and firm” whites, according to the US Department of Agriculture, or USDA, with yolks that are high, round and practically free from defects, with clean, unbroken shells. Grade A eggs are similar to Grade AA eggs but with less firm whites.Grade B eggs tend to have thinner whites and wider yolks. Their shells are also unbroken, but may show light stains. These eggs are rarely found in retail stores because they are often used to make liquid, frozen and dried egg products.Cage-freeEggs labeled “USDA-grade cage-free” are from hens that are able to roam vertically and horizontally in indoor houses. They must have access to fresh food and water, litter and protection from predators. These systems vary from farm to farm, but they must allow hens to exhibit natural behaviors and include scratch areas, perches and nests.In the last 10 years, hundreds of companies have committed to going entirely cage-free, and the country’s cage-free egg-laying flock increased by more than 10.5m hens in the first six months of 2023.But it’s important to remember that cage-free does not equal cruelty-free. “Cage-free means the bird lives indoors, but not in a cage,” said Carolyn Dimitri, director of NYU’s graduate food studies program. “This bird probably lives in crowded conditions.”Hormone-freeNo hormones are used in the raising of chickens. In fact, federal regulations banned their use in the 1950s, so if you see labels that say “no hormones”, it’s simply a marketing tactic and is not related to more humane treatment of hens or the health of an egg.Certified organicCertified organic eggs come from uncaged organic hens, which are fed organic feed free of animal byproducts, GMO crops or synthetic fertilizers, pesticides or herbicides. Regulated, certified and inspected by the USDA, organic flocks must have access to outdoor spaces and be raised without growth hormones (as all chickens, even non-organic ones, are) or antibiotics.But the organic label hasn’t always met consumer expectations for animal welfare, since organic layer hens still often live in crowded conditions. Some producers confine their hens to barns with concrete porches instead of true outdoor space. A new rule, however, mandates indoor and outdoor space requirements, thanks to the efforts of advocacy groups. But it doesn’t go into effect until 2029, said Freund, “so in the meantime, consumers should still seek out welfare-certified options”. The Cornucopia Institute, a non-profit food and farm watchdog group, maintains a score card to help consumers decide which organic eggs are best.Free-rangeRegulated by the USDA, free-range eggs are produced by hens that are able to roam vertically and horizontally in indoor houses, have access to fresh food and water and continuous access to the outdoors during their laying cycle. The outdoor area may be fenced and/or covered with netting-like material.Like cage-free hens, free-range hens must be allowed to exhibit natural behaviors and include scratch areas, perches and nests and have access to litter, have protection from predators and be able to move in the barn. Animal welfare advocates say free-range is a loosely defined term and since the type of outdoor space can vary, the label may fall short of shoppers’ expectations.Certified humaneNot affiliated with the USDA, Certified Humane is a project of Humane Farm Animal Care, a third-party non-profit certification program. The Certified Humane label means the hens’ environment takes into account their welfare needs and protects them from physical and thermal discomfort, fear and distress and allows them to perform their natural behavior. No cages or aviary systems that confine birds are allowed and laying hens must be provided with nest boxes.Pasture-raisedHens raised entirely on pasture can eat bugs, worms and grass and have ample room to roam, scratch, dust-bathe and engage in all of their natural behaviors. Since the term “pasture-raised” has no legal definition and is not regulated by the USDA, consumers should look for eggs that have additional labels and certifications to ensure the term is not misused by producers. Once considered a luxury item, rising demand helped shrink the price gap and increase supply. Pasture-raised eggs can be richer in flavor and more nutritious than caged eggs since the hens spend time outdoors and eat a more diverse diet. When hens have access to natural forage, the need for large-scale feed production and transportation is reduced, which results in fewer emissions compared to conventional egg production.What if a carton of eggs has none of these labels?The majority of the 300m chickens involved in egg production in the US are still raised in long, windowless sheds in rows of stacked battery cages. These caged hens are afforded only 67 sq ins of space on average – smaller than a sheet of letter-sized paper – and denied natural behaviors such as nesting, perching and dust-bathing. Factory-farmed eggs are often advertised as being “natural” or using “no antibiotics ever” and their cartons can paint misleading scenes of humane treatment on idyllic farms. If these cartons are not labeled as being “cage-free”, “free-range”, “organic” or “pasture-raised”, you can assume they came from factory farm hens who are confined to such a degree that they can’t even flap their wings.How do I eat ethically without breaking the bank?While eggs are still one of the cheapest forms of animal protein, prices have soared in recent years, now sometimes exceeding $1 per egg. “Higher-welfare animal products sometimes do cost more because farmers are investing in better conditions and treatment, as opposed to factory farming, which relies on cruel practices and externalized costs to make a cheap product,” said Freund. Since brands commonly charge more for claims such as “humane”, “natural” and even “free-range”, which are not backed by strong definitions or on-farm audits, shoppers can be easily misled.Experts suggest buying higher-welfare eggs like pasture-raised for special meals or reducing the number of eggs you eat each week. Another option is to supplement your diet with plant-based options. The ASPCA’s Shop with Your Heart Grocery List allows shoppers to find the lowest-cost, highest-welfare products.How do I know what kinds of eggs restaurants are using?The short answer is, you often don’t. While some restaurants may disclose what kinds of eggs they use for egg-centric dishes on a menu, it’s harder to know what types of eggs are featured in items such as baked goods, pastas, dressings and desserts. In 2018, Panera petitioned the FDA to know what an “egg” was exactly, stating that many of its competitors sell egg patties that contain more than five ingredients.McDonald’s recently announced they’re using 100% cage-free eggs, and Panera has committed to sourcing 100% cage-free eggs across all products by the end of 2025. Many restaurants use frozen, refrigerated liquid and dried forms of eggs whether they’re cage-free or not. The best way to find out is to ask the restaurants you patronize, but that doesn’t always mean you’ll get a clear answer.Are eggs from the farmers’ market automatically good?Farmers market eggs are richer in color and taste. Illustration: Olivia de Salve Villedieu/The GuardianFarmers’ markets can be great places to find alternatives to factory-farmed food. The yolks of farm-fresh eggs are often richer in color and taste since their food sources are of a higher quality than factory-farm chickens. Of course, not all farmers’ markets are created equal and just because a product is local doesn’t necessarily mean it’s better. Ask the farmer for details on how their hens are raised since not all farms raise animals the same way.What about vegan alternatives?For people looking for plant-based alternatives, there are a host of options. Simply Eggless’s vegan eggs are made from lupin beans and are available as a liquid, patty, bite and omelet, while Crafty Counter’s hard-boiled WunderEggs are created from cashews, almonds and other plant-based ingredients. For vegan baking, Bob’s Red Mill’s gluten-free Egg Replacer and Ener-G’s Egg Replacer are both made primarily from potato starch and tapioca flour, and Neat’s Egg Mixx is crafted from chia seeds and garbanzo beans.While vegan eggs that mimic the look, texture and taste of real eggs tend to be more expensive than eggs from hens, many of the flour-like products that replace eggs in baking are affordable (a 16oz bag can equal around 100 eggs). Experts say it’s critical for plant-based companies to scale up production and optimize ingredients so products can be competitively priced for consumers.The verdict: so what should I buy?When considering animal welfare, environmental impact and health, certified-organic, pasture-raised eggs are the winner.“The birds are able to live a free life that suits their biological needs, and they are not exposed to synthetic chemicals on the pasture or through their feed,” said NYU’s Dimitri. “This egg has the best animal-welfare and environmental lifestyle.” One study found that pasture-raised eggs had significantly more omega-3 fats and vitamin E compared to those from caged hens.When looking solely at animal welfare, experts point to eggs from hens raised on pasture as the best option. “Shoppers should look for eggs from farms that are certified by the Animal Welfare Approved program, which requires that animals are on pasture throughout their lives, or can look for the Certified Humane seal with the words ‘pasture-raised’ on the package,” said the ASPCA’s Freund.Even if shoppers can’t find one of these options, experts say most retail stores carry some Certified Humane products, even if they’re not pasture-raised. Those products at least ensure that animals are never in cages and are raised in enriched indoor spaces or have access to large outdoor spaces.

A “scientific sandbox” lets researchers explore the evolution of vision systems

The AI-powered tool could inform the design of better sensors and cameras for robots or autonomous vehicles.

Why did humans evolve the eyes we have today?While scientists can’t go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that exist in nature, a new computational framework developed by MIT researchers allows them to explore this evolution in artificial intelligence agents.The framework they developed, in which embodied AI agents evolve eyes and learn to see over many generations, is like a “scientific sandbox” that allows researchers to recreate different evolutionary trees. The user does this by changing the structure of the world and the tasks AI agents complete, such as finding food or telling objects apart.This allows them to study why one animal may have evolved simple, light-sensitive patches as eyes, while another has complex, camera-type eyes.The researchers’ experiments with this framework showcase how tasks drove eye evolution in the agents. For instance, they found that navigation tasks often led to the evolution of compound eyes with many individual units, like the eyes of insects and crustaceans.On the other hand, if agents focused on object discrimination, they were more likely to evolve camera-type eyes with irises and retinas.This framework could enable scientists to probe “what-if” questions about vision systems that are difficult to study experimentally. It could also guide the design of novel sensors and cameras for robots, drones, and wearable devices that balance performance with real-world constraints like energy efficiency and manufacturability.“While we can never go back and figure out every detail of how evolution took place, in this work we’ve created an environment where we can, in a sense, recreate evolution and probe the environment in all these different ways. This method of doing science opens to the door to a lot of possibilities,” says Kushagra Tiwary, a graduate student at the MIT Media Lab and co-lead author of a paper on this research.He is joined on the paper by co-lead author and fellow graduate student Aaron Young; graduate student Tzofi Klinghoffer; former postdoc Akshat Dave, who is now an assistant professor at Stony Brook University; Tomaso Poggio, the Eugene McDermott Professor in the Department of Brain and Cognitive Sciences, an investigator in the McGovern Institute, and co-director of the Center for Brains, Minds, and Machines; co-senior authors Brian Cheung, a postdoc in the  Center for Brains, Minds, and Machines and an incoming assistant professor at the University of California San Francisco; and Ramesh Raskar, associate professor of media arts and sciences and leader of the Camera Culture Group at MIT; as well as others at Rice University and Lund University. The research appears today in Science Advances.Building a scientific sandboxThe paper began as a conversation among the researchers about discovering new vision systems that could be useful in different fields, like robotics. To test their “what-if” questions, the researchers decided to use AI to explore the many evolutionary possibilities.“What-if questions inspired me when I was growing up to study science. With AI, we have a unique opportunity to create these embodied agents that allow us to ask the kinds of questions that would usually be impossible to answer,” Tiwary says.To build this evolutionary sandbox, the researchers took all the elements of a camera, like the sensors, lenses, apertures, and processors, and converted them into parameters that an embodied AI agent could learn.They used those building blocks as the starting point for an algorithmic learning mechanism an agent would use as it evolved eyes over time.“We couldn’t simulate the entire universe atom-by-atom. It was challenging to determine which ingredients we needed, which ingredients we didn’t need, and how to allocate resources over those different elements,” Cheung says.In their framework, this evolutionary algorithm can choose which elements to evolve based on the constraints of the environment and the task of the agent.Each environment has a single task, such as navigation, food identification, or prey tracking, designed to mimic real visual tasks animals must overcome to survive. The agents start with a single photoreceptor that looks out at the world and an associated neural network model that processes visual information.Then, over each agent’s lifetime, it is trained using reinforcement learning, a trial-and-error technique where the agent is rewarded for accomplishing the goal of its task. The environment also incorporates constraints, like a certain number of pixels for an agent’s visual sensors.“These constraints drive the design process, the same way we have physical constraints in our world, like the physics of light, that have driven the design of our own eyes,” Tiwary says.Over many generations, agents evolve different elements of vision systems that maximize rewards.Their framework uses a genetic encoding mechanism to computationally mimic evolution, where individual genes mutate to control an agent’s development.For instance, morphological genes capture how the agent views the environment and control eye placement; optical genes determine how the eye interacts with light and dictate the number of photoreceptors; and neural genes control the learning capacity of the agents.Testing hypothesesWhen the researchers set up experiments in this framework, they found that tasks had a major influence on the vision systems the agents evolved.For instance, agents that were focused on navigation tasks developed eyes designed to maximize spatial awareness through low-resolution sensing, while agents tasked with detecting objects developed eyes focused more on frontal acuity, rather than peripheral vision.Another experiment indicated that a bigger brain isn’t always better when it comes to processing visual information. Only so much visual information can go into the system at a time, based on physical constraints like the number of photoreceptors in the eyes.“At some point a bigger brain doesn’t help the agents at all, and in nature that would be a waste of resources,” Cheung says.In the future, the researchers want to use this simulator to explore the best vision systems for specific applications, which could help scientists develop task-specific sensors and cameras. They also want to integrate LLMs into their framework to make it easier for users to ask “what-if” questions and study additional possibilities.“There’s a real benefit that comes from asking questions in a more imaginative way. I hope this inspires others to create larger frameworks, where instead of focusing on narrow questions that cover a specific area, they are looking to answer questions with a much wider scope,” Cheung says.This work was supported, in part, by the Center for Brains, Minds, and Machines and the Defense Advanced Research Projects Agency (DARPA) Mathematics for the Discovery of Algorithms and Architectures (DIAL) program.

Common household rat poisons found to pose unacceptable risk to wildlife as animal advocates push for ban

Environmentalists say proposed temporary suspension of second-generation anticoagulant rodenticides ‘doesn’t go far enough’Follow our Australia news live blog for latest updatesGet our breaking news email, free app or daily news podcastCommonly available rat poisons pose unacceptable risks to native wildlife, according to a government review that has stopped short of recommending a blanket ban on the products, to the consternation of animal advocates.The long-awaited review of first- and second-generation anticoagulant rodenticides – FGARs and SGARs – has recommended the cancellation of some products, but a large array of waxes, pellets and blocks could continue to be sold to consumers subject to stricter labelling and conditions of use.

Commonly available rat poisons pose unacceptable risks to native wildlife, according to a government review that has stopped short of recommending a blanket ban on the products, to the consternation of animal advocates.The long-awaited review of first- and second-generation anticoagulant rodenticides – FGARs and SGARs – has recommended the cancellation of some products, but a large array of waxes, pellets and blocks could continue to be sold to consumers subject to stricter labelling and conditions of use.Baits containing anticoagulant rodenticides are widely available in supermarkets and garden stores such as Bunnings, Coles and Woolworths.The baits have come under scrutiny because they have been found in dead native animals such as tawny frogmouths, powerful owls and quolls that had eaten poisoned rats and mice.The second-generation products are more toxic and are banned from public sale in the United States and parts of Canada and highly restricted in the European Union.Commercially available rat poisons have been found in dead native animals. Photograph: Fabio De Paola/The GuardianConsumers can identify SGARs in Australia by checking whether they contain one of the following active ingredients: brodifacoum, bromadiolone, difethialone, difenacoum and flocoumafen. There are three FGAR active ingredients registered for use in Australia: warfarin, coumatetralyl and diphacinone.The Australian Pesticides and Veterinary Medicines Authority (APVMA), in response to the review which was published Tuesday, has proposed a temporary suspension of SGARs while public consultation about the recommendations is under way. If the suspension goes ahead the APVMA said the affected products could still be used, but only in accordance with the proposed stricter conditions.“If suspended, the importation or manufacture of SGARs would be illegal. They could only be sold if they meet the new strict conditions around pack size and use,” a spokesperson said.Holly Parsons, of BirdLife Australia, said the review “doesn’t go far enough and crucially, fails to address secondary poisoning that is killing owls and birds of prey” such as when, for example, a native bird ate a poisoned rat.“Despite overwhelming evidence provided in support of the complete removal of SGARs from public sale, we’re yet to see proposed restrictions that come close to achieving this,” Parsons said.She said consumers should be able to “walk into stores under the assumption that the products available to them aren’t going to inadvertently kill native animals” but the APVMA has put “the responsibility on to the consumer with an expectation that labels are fully read and followed – and we know that won’t be the case”.The review also recommended cancelling the registration of anticoagulant rodenticides baits that come in powder and liquid form or which do not contain dyes or bittering agents, finding they do not meet safety criteria.But it found other baits sold as waxes, pellets and blocks could continue to be sold to consumers with some changes to labelling and conditions of use.Sign up: AU Breaking News emailThe APVMA found that under “current instructions” it could not be satisfied that these types of products would not have unintended, harmful effects on non-target animals, including native wildlife, nor that they would not pose undue safety risks to people who handled them including vulnerable people such as children.But it found the conditions of product registration and other “relevant particulars” could be varied in such a way as to allow the authority “to be satisfied that products will meet the safety criteria”.Some of the proposed new instructions would include limiting mice baits to indoor use only when in tamper-resistant bait stations; placing outdoor rat baits in tamper-proof stations within two metres of outside a building; changes to pack sizes; and tighter directions for the clean-up and disposal of carcasses and uneaten baits.The recommendations are subject to three months of public consultation before the authority makes a final decision.John White is an associate professor of wildlife and conservation biology at Deakin University. In 2023 he worked with a team of researchers that studied rat poison in dead tawny frogmouths and owls, who found 95% of frogmouths had rodenticides in their livers and 68% of frogmouths tested had liver rodenticide levels consistent with causing death or significant toxicological impacts.He said the authority’s proposed changes failed to properly tackle the problem that SGARS, from an environmental perspective, were “just too toxic”.White said even if the authority tightened the conditions of use and labelling rules there was no guarantee that consumers would follow new instructions. “We should be completely banning these things, not tinkering at the edges,” he said.A spokesperson for Woolworths said the supermarket would await the APVMA’s final recommendations “to inform a responsible approach to these products, together with the suppliers of them”.They said the chain stocked “a small range of second-generation anticoagulant rodenticides for customers who might have a problem with rats or mice in their home, workplace, and especially in rural areas where it’s important for customers to have access to these products” while also selling “a number of alternative options”.Bunnings and Coles declined to comment.

Trail Cameras in Vermont Captured Something Strange: Moths Sipping a Moose's Tears

Tear-drinking, known as lachryphagy, has mostly been observed in the tropics, so scientists were somewhat surprised to find the unusual behavior so far north

Trail Cameras in Vermont Captured Something Strange: Moths Sipping a Moose’s Tears Tear-drinking, known as lachryphagy, has mostly been observed in the tropics, so scientists were somewhat surprised to find the unusual behavior so far north Sarah Kuta - Daily Correspondent December 16, 2025 8:49 a.m. A trail camera in Vermont captured 80 photos of moths fluttering around a moose's head, likely slurping up its tears. Vermont Fish and Wildlife Department Laurence Clarfeld was sifting through images captured by a trail camera in Vermont when he came across a photo that stopped him in his tracks. Clarfeld, an environmental scientist at the University of Vermont, knew he was looking at a moose. But, beyond that, he was totally perplexed. “It almost looked like the moose had two [additional] eyes,” he tells Scientific American’s Gennaro Tomma. When he flipped through more photos in the sequence, Clarfeld finally understood what he was seeing: Moths were sipping tears straight from the ungulate’s eyes. Scientists have observed this unusual phenomenon, known as lachryphagy, among other types of animals. But, as far as anyone knows, the photos represent the first documented evidence of moths drinking moose tears. Clarfeld and his colleagues describe the encounter in a new paper published November 20 in the journal Ecosphere.  Moths seen drinking moose tears for first time ever The photos were captured in the early morning hours of June 19, 2024, in the Green Mountain National Forest, a large swath of protected woodlands in southern Vermont. Researchers had deployed them as part of an ongoing wildlife survey by the Vermont Fish and Wildlife Department. In total, the camera captured 80 snapshots of the moths fluttering around a moose’s head. The photos don’t specifically show the moths’ proboscises, the long, slender, straw-like mouthparts they use to suck nectar from flowers. But lachryphagy is the “most plausible explanation,” the researchers write in the paper. Roughly a year later, a colleague captured video footage that appeared to show the same thing—moths hovering around a moose’s eyes, per Scientific American. Scientists have previously observed moths, bees and butterflies feeding on the tears of other animals. They’ve documented solitary bees drinking the tears of yellow-spotted river turtles in Ecuador, stingless bees harvesting human tears in Thailand, erebid moths feasting on the tears of ringed kingfishers in Colombia and erebid moths slurping up the tears of sleeping black-chinned antbirds in Brazil. But most of these instances have occurred in subtropical and tropical regions. Only one known case of lachryphagy has been documented outside the tropics, according to the researchers: a moth eating the tears of a horse in Arkansas. At first, researcher Laurence Clarfeld didn't know what he was seeing when he spotted moths hovering around a moose's eyes. Vermont Fish and Wildlife Department It may be that lachryphagy is simply more common in the tropics. But it’s also possible that “not a lot of scientists are looking in [other] places,” Akito Kawahara, an entomologist at the Florida Museum of Natural History who was not involved with the research, tells Scientific American. Why do moths and other insects feed on tears? It’s not entirely clear, but scientists suspect they may be seeking out certain essential nutrients, like sodium, during periods when those substances may be harder to find elsewhere. They may also be looking for protein boost. Insects typically get protein from plant nectar, but tears may be a handy backup. “Vertebrate fluids are the main alternative source for obtaining proteins,” Leandro Moraes, a biologist at the University of São Paulo who observed tear-feeding moths in Brazil, told National Geographic’s Sandrine Ceurstemont in 2018. Did you know? Resourceful insects Aside from tears, butterflies and moths have been known to take advantage of whatever resources are available, gathering up nutrient-rich liquids in and around soil, feces and carrion, including sweat and blood. Scientists call this feeding behavior “puddling.” Though lachryphagy appears to be relatively rare in nature, researchers still want to learn more about this unusual behavior. The tear drinker obviously benefits, but what about the tear supplier? For now, the relationship appears to be fairly one-sided—and might even be harmful to the host. In moose, for instance, eye-visiting moths could be transmitting pathogens that cause keratoconjunctivitis, which can lead to eye lesions and “significant health impacts,” the researchers write in the paper. For now, though, that’s just a hypothesis. Now that tear-drinking has been observed outside its typical range, the researchers are curious to know where else this behavior might be taking place, and among which other species. They’re encouraging wildlife scientists to keep an eye out because lachryphagy might ultimately be “more widespread than the lack of past records would suggest,” they write.

Costa Rica Shifts Toward Regenerative Tourism Alongside Other Nations

Costa Rica has long stood out for its commitment to protecting natural areas through tourism. Now, our country joins a growing number of nations that push beyond basic protection. They aim to restore and improve ecosystems damaged by past activities. This approach, called regenerative tourism, changes how visitors interact with places they travel to. In Costa Rica, tourism generates over 8 percent of the national economy and supports hundreds of thousands of jobs. For decades, the focus stayed on sustainability—keeping beaches clean, forests intact, and wildlife safe without causing more harm. But recent efforts show a clear move to regeneration. Local projects work to rebuild habitats, boost biodiversity, and strengthen communities hit hard by environmental changes. Take Punta Leona, a coastal area in Puntarenas. Hotels there add a small fee to each booking, with funds going directly to conserve local plants and animals. This has helped protect scarlet macaws and other species facing threats from habitat loss. In the Arenal area, Rancho Margot operates as a self-sustaining farm and lodge. It grows its own food, recycles water, and teaches guests how to plant trees that restore soil eroded by old farming practices. These actions do more than maintain the status quo; they repair what was lost. Costa Rica’s government backs this trend. The Tourism Board promotes programs that encourage visitors to join conservation work, such as planting mangroves along the Pacific coast or monitoring sea turtles in Tortuguero. A group called Costa Rica Regenerativa advises businesses on how to integrate regeneration into their operations. They focus on holistic plans that cover social, cultural, and environmental needs. As a result, areas like Monteverde see improved cloud forest health, with reforestation efforts bringing back native species absent for years. This shift aligns with global patterns. New Zealand sets a strong example. Its tourism authority invites travelers to participate in restoring native forests and waterways. In places like Rotorua, canopy tours fund projects that remove invasive plants and protect geothermal sites. The country reports higher visitor satisfaction when people contribute to these efforts, leading to longer stays and more repeat trips. Saudi Arabia takes a different path but shares the goal. It invests in large-scale regeneration in desert regions, turning arid lands into green spaces through water management and planting programs. Tourism there now includes experiences where guests help with these restorations, drawing interest from eco-conscious travelers. Finland emphasizes carbon neutrality in its northern landscapes. Cities like Helsinki offer tours that involve cleaning up lakes and planting boreal forests. This not only offsets travel emissions but also enhances wildlife corridors for species like reindeer. Ecuador’s Galápagos Islands provide another case. Strict rules limit visitor numbers, but regenerative programs let people assist in removing invasive species and monitoring marine life. Revenue from these activities funds habitat restoration, helping giant tortoises and other endemic animals thrive. In Mexico, Playa Viva on the Pacific coast runs as a regenerative resort. It restores mangroves and coastal dunes while involving local communities in decision-making. Guests leave with a sense of having improved the place they visited. These examples show regenerative tourism spreading across continents. It responds to rising awareness of climate change and biodiversity loss. Travelers today seek meaningful trips that give back, and nations like Costa Rica benefit from this demand. Studies from the World Travel & Tourism Council indicate that regenerative practices can increase tourism revenue by up to 20 percent in participating areas, as they attract higher-spending visitors. Challenges remain. Mass tourism can strain resources, as seen in some Costa Rican beaches where overcrowding leads to pollution. To counter this, experts call for better regulations and education. Community involvement stays key—local people must lead these initiatives to ensure they meet real needs. Looking ahead, Costa Rica plans to expand regenerative models nationwide. Partnerships with international organizations aim to share knowledge with other countries. This positions the nation as a guide in the field, showing how tourism can heal rather than just preserve. As more nations adopt this model, the travel industry may see lasting change. For us here in Costa Rica, it means building a healthier future for our land and people.

In Alaska’s Warming Arctic, Photos Show an Indigenous Elder Passing Down Hunting Traditions

An Inupiaq elder teaches his great-grandson to hunt in rapidly warming Northwest Alaska where thinning ice, shifting caribou migrations and severe storms are reshaping life

KOTZEBUE, Alaska (AP) — The low autumn light turned the tundra gold as James Schaeffer, 7, and his cousin Charles Gallahorn, 10, raced down a dirt path by the cemetery on the edge of town. Permafrost thaw had buckled the ground, tilting wooden cross grave markers sideways. The boys took turns smashing slabs of ice that had formed in puddles across the warped road.Their great-grandfather, Roswell Schaeffer, 78, trailed behind. What was a playground to the kids was, for Schaeffer – an Inupiaq elder and prolific hunter – a reminder of what warming temperatures had undone: the stable ice he once hunted seals on, the permafrost cellars that kept food frozen all summer, the salmon runs and caribou migrations that once defined the seasons.Now another pressure loomed. A 211-mile mining road that would cut through caribou and salmon habitat was approved by the Trump administration this fall, though the project still faces lawsuits and opposition from environmental and native groups. Schaeffer and other critics worry it could open the region to outside hunters and further devastate already declining herds. “If we lose our caribou – both from climate change and overhunting – we’ll never be the same,” he said. “We’re going to lose our culture totally.”Still, Schaeffer insists on taking the next generation out on the land, even when the animals don’t come. It was late September and he and James would normally have been at their camp hunting caribou. But the herd has been migrating later each year and still hadn’t arrived – a pattern scientists link to climate change, mostly caused by the burning of oil, gas and coal. So instead of caribou, they scanned the tundra for swans, ptarmigan and ducks.Caribou antlers are stacked outside Schaeffer's home. Traditional seal hooks and whale harpoons hang in his hunting shed. Inside, a photograph of him with a hunted beluga is mounted on the wall beside the head of a dall sheep and a traditional mask his daughter Aakatchaq made from caribou hide and lynx fur.He got his first caribou at 14 and began taking his own children out at 7. James made his first caribou kill this past spring with a .22 rifle. He teaches James what his father taught him: that power comes from giving food and a hunter’s responsibility is to feed the elders.“When you’re raised an Inupiaq, your whole being is to make sure the elders have food,” he said.But even as he passes down those lessons, Schaeffer worries there won’t be enough to sustain the next generation – or to sustain him. “The reason I’ve been a successful hunter is the firm belief that, when I become old, people will feed me,” he said. “My great-grandson and my grandson are my future for food.” That future feels tenuous These days, they’re eating less hunted food and relying more on farmed chicken and processed goods from the store. The caribou are fewer, the salmon scarcer, the storms more severe. Record rainfall battered Northwest Alaska this year, flooding Schaeffer’s backyard twice this fall alone. He worries about the toll on wildlife and whether his grandchildren will be able to live in Kotzebue as the changes accelerate.“It’s kind of scary to think about what’s going to happen,” he said.That afternoon, James ducked into the bed of Schaeffer’s truck and aimed into the water. He shot two ducks. Schaeffer helped him into waders – waterproof overalls – so they could collect them and bring them home for dinner, but the tide was too high. They had to turn back without collecting the ducks. The changes weigh on others, too. Schaeffer’s friend, writer and commercial fisherman Seth Kantner grew up along the Kobuk River, where caribou once reliably crossed by the hundreds of thousands. “I can hardly stand how lonely it feels without all the caribou that used to be here,” he said. “This road is the largest threat. But right beside it is climate change.”The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.
