‘The Mountain Wagtail’: How Pollution and Mining Are Destroying Kyrgyzstan

As mining operations destroy millennia-old glaciers, Kyrgyzstani director Begaly Nargozu’s new film reflects a disappearing landscape and culture. The post ‘The Mountain Wagtail’: How Pollution and Mining Are Destroying Kyrgyzstan appeared first on The Revelator.

Every winter young Altyn, the protagonist of Kyrgyzstani director Begaly Nargozu’s 2023 film The Mountain Wagtail, would mount her horse, leave her village in the valley, and head to the syrt, an unchanging landscape of snow and glaciers stretching across the mountaintops of Kyrgyzstan, to help her nomadic grandparents herd their yaks. Altyn’s innocent, kind-hearted nature — nurtured by the beauty of the icy landscape and her grandparents’ reverence for it — is tested when, in the twilight of her teenage years, she moves to the capital of Bishkek to attend university. Staying with her older sister, a fully urbanized entrepreneur with a disdain for all things rural, Altyn soon finds herself confronted by all the trappings and evils of modern-day society, from substance abuse and sexual assault to domestic violence and environmental pollution. The Mountain Wagtail premiered in 2023 and has recently played at ecology-themed Sprouts Film Festival in Amsterdam and other film festivals across Europe and Asia. Nargozu says his village, like Altyn’s unnamed hometown, is surrounded by “holy mountains which hundreds of people visit every day to pray and ask for a better life.” His tale of Altyn’s journey to the city echoes the journeys of many young Kyrgyzstani women as heavy industry and mining operations turn the countryside increasingly inhospitable. “Tons of dust rise into the air each day from mining development and settle on the surrounding glaciers,” he tells The Revelator. “Millions of cubes of ice are melted, billions of tons of harmful substances are poured into rivers. Every year, there are fewer pastures and grasslands. The traditional pastoral life of the highlands is being destroyed, and so people leave the mountains and go to the cities, where living conditions are poorer still.” In addition to a lack of affordable housing, unauthorized construction, and poor waste management, Bishkek’s air quality is among the worst in the world, resulting in roughly 4,000 premature deaths each year. Contributing factors range from factory and vehicle emissions to the country’s continued and widespread use of coal. Sharing the blame is Bishkek’s landfill, originally dug by the Soviet Union, which was too small to keep up with the city’s growing population and, as a result, regularly caught fire and filled the air with toxic fumes. (After years of struggling to procure international investment and circumvent government corruption, a new landfill opened in 2023.) Historically, says Nargozu, “the Kyrgyz did not treat the mountains as consumers; they did not look for valuable materials there, blowing up anything and everything. On the contrary, they worshiped and prayed to them, living for thousands of years without major problems with nature, in harmony.” According to Nargozu, it was only with the advent of the colonization of imperial Russia that the extraction of valuable metals and toxic substances from the Kyrgyz mountains on an industrial scale began. Official film poster for The Mountain Wagtail. The distinction at the center of The Mountain Wagtail isn’t between urban and rural but syrt and non-syrt. Altyn’s village, though isolated, pastoral, and idyllic by western standards, is presented as a kind of Bishkek writ small: a sign of the future that awaits the Kyrgyzstani countryside.  Only the syrt remains free of the spiritual corruption radiating from Bishkek. Up there, accompanied only by snow, sun, yaks, and an ecologist researching the melting glaciers, Altyn’s grandparents live in unceasing peace and happiness. The only couple in the film that treats one another with kindness and respect, Nargozu’s screenplay refers to them as “celestial beings.” But they are also an endangered species. The Mountain Wagtail’s mixed reception inside Kyrgyzstan reflects the hold heavy industry has on the country and its culture. When Nargozu showed the film at the Ala-Too cinema in the capital in 2023, he says it was warmly received by creatives and the intelligentsia. Government officials were less enthusiastic, though. When the film began receiving awards from international festivals, Nargozu said they asked him: “Why spread negativity about Kyrgyzstan throughout the world? We need to be more patriotic and show only our good side.” “It looks depressing,” Nargozu says of Kyrgyzstan’s future. “Every year we export tons and tons of pure gold, yet we remain among the poorest countries of the world. Should we continue to mine gold if — instead of happiness — it only brings us closer to environmental disaster?” In search of answers, he looks to the same place Altyn does when she feels lost — the syrt: “Maybe we need to live like our ancestors, protecting nature and the traditional, pastoral way of life of the mountaineers.” In The Mountain Wagtail, he uses the color white to symbolize the natural purity of the Mongu-Ata glacier as well as Altyn’s moral purity. “Just as rivers originate from mountain lakes and glaciers, so Altyn’s spiritual purity begins with her grandfather and grandmother. She is their spiritual heir,” Nargozu says. “The film begins with the snow-capped syrt and white-topped mountain peaks and ends at the Mongu-Ata glacier and the sacred silver lake Kumush-Kol. Such is the fate of Altyn, who descends from the snow-white mountains and, having gone through a series of trials in the city, returns to her own roots, to the traditional way of life and fundamental values ​​of her people.” Watch the trailer to Mountain Wagtail below: Trailer: The Mountain Wagtail | SproutsFF24 from Sprouts Film Festival on Vimeo.

Paris Mayor Defies Poo Threats to Swim in Seine, and Prove a Point

French politicians’ pledge to make swimming possible in the iconic river is a way to ward off criticism about the cost of the clean up operation.

On a sunny Wednesday in Paris, the city’s Mayor inches down a ladder into the blue-brown water of the river Seine, one cautious step at a time. After a few seconds, once Anne Hidalgo’s wetsuit is completely submerged, she dons small dark goggles and dunks her face underwater—proving to the photographers and TV cameras following her by boat that she believes this water is clean.This is a historic moment for Paris, which many people believed was not going to happen. Swimming in The Seine has been banned for the past century and a river clean enough for a political photo-op has long been an ambition among French lawmakers.This clean-up operation has become the centerpiece of what Paris is calling “The Greenest Ever Games” and the legacy of this effort is expected to last. After Hidalgo dries off, The Seine will stage several Olympic swimming events before three public bathing areas will open in the Games’ aftermath.But the €1.4 billion ($1.5bn) clean-up operation is not really about swimming. The ability to bathe in The Seine is simply a side show; payback to Parisians for the use of massive public funds to complete such an ambitious river restoration project. Instead, the real goal is to protect a source of drinking water and help life return to the river, so fish—such as the famous Parisian catfish—can continue to thrive.The promise of swimming is intended to guard against the kind of criticism that pits environmental projects against the needs of ordinary people. Online accounts have already pledged to poop in The Seine en masse under the hashtag #JeChieDansLaSeine, or #IPooInTheSeine, to protest the amount of money spent on the project, as ordinary people struggle with the cost of living. (There is no evidence anyone actually did this, and whoever set up the original website did not reply to WIRED’s request for comment.)“Having this totemic goal of swimming in the river is something that really helps politically … because it’s very expensive,” says Caroline Whalley, a water pollution expert at the European Environment Agency. “It's a way to get public support, because they can see the benefit. There's something in it for them.”The Seine started to die at the onset of the 20th century. For 50 years, raw sewage was released into the river, prompting the city to put an end to idyllic scenes of families cavorting in the water, ruling bathing in the water (mostly) illegal from 1923. In the years that followed, The Seine became a grim symbol of industrialization.“There was no life in the river Seine during these 50 years,” says Jean-Marie Mouchel, a professor at the Sorbonne University, who has been studying the river since the 80s. The sewage sapped the water of oxygen and created obstacles for river traffic. “There was so much sediment and deposits from the sewers that [they created] mountains of deposits on the bottom [of the river],” says Mouchel, “so boats couldn't even pass through.”

Storms, fires and floods: Blue Mountains Jenolan Caves to close after series of unforgiving weather

The world’s oldest known open caves have been closed to visitors after the only roads in were destroyed or damaged by storms, fires and floods.The Jenolan Caves, in the Blue Mountains region west of Sydney, are now impossible to access by road, after months of heavy rain forced the only remaining road to close for repairs for 18 months.The caves have faced intermittent shutdowns over the last five years as a series of severe weather events damaged infrastructure and made the alternative route unsafe for drivers.“Our feature is nature, and we’re subject to the vagaries of that,” Andrew Le Lievre said, acting director of the Jenolan Caves Reserve Trust, which manages the historic precinct.“Everything has a use-by date and unfortunately the road reached it, and now we’ve got to repair it,” he said.Roads and buildings surrounding the Jenolan Caves suffered heavy rain damage in April 2024. Photograph: NSW Department of Climate Change, Energy, the Environment and WaterAbout 230,000 visitors each year accessed the public caves and surrounding walking trails, and accommodation before the black summer bushfires in 2019-20, which burned 80% of the Blue Mountains world heritage area.Those bushfires ripped $2.8bn almost instantly from Australia’s economy by crushing spending on tourism, according to a University of Sydney study.The entire Jenolan Caves precinct is now closed to the public as roadworks begin, the latest in a string of severe weather hits to tourism across Australia.A former chair of the trust, Richard Mackay said it was “very disappointing” that the caves had been closed off.“They really have had a very bad run of luck with major storm and flooding events on top of bushfires, and that has combined literally into a perfect storm,” he said.“It is tragic that such an important cave conservation area and part of the greater Blue Mountains world heritage area is not going to be accessible to the community.”Visitors inside the Jenolan Caves before the precinct closed down in 2024.

P-22 lived an epic and tragic life in Griffith Park. Would a new mountain lion fare any better?

A mountain lion spotted at the edge of Griffith Park last month recalled the park's former feline king, P-22. If the new cougar stays, he'll face the same challenges as his predecessor.

A sleek mountain lion filmed from behind the wheel of a Tesla on the edge of Griffith Park last month triggered a collective double take in Los Angeles.Not long ago, the park’s long-reigning king — the cougar known as P-22 — stalked the same hills.While P-22’s stint in Hollywood brought him fame and devotion — landing him on T-shirts and culminating in a sold-out memorial — it also came with deadly trappings inherent to his urban-adjacent environment. Rat poison and car collisions battered him from the inside out. He was captured and euthanized in late 2022, deemed too sick to return to the wild because of injuries and infection.A mountain lion living in Griffith Park today would likely suffer a similar fate. Aggressive and impactful reporting on climate change, the environment, health and science. “Has anything changed, in some respects, in Griffith Park? No,” said Beth Pratt of the National Wildlife Federation, a vocal booster for Southern California mountain lions, P-22 in particular. “As much as people are really excited about this cat, a lot, including myself, are worried about him.”Cars still whiz along freeways that isolate small populations of lions and perilously limit genetic diversity. Some types of rat poison, which travels up the food chain to an apex predator like a puma, can still be bought at the hardware store.But P-22‘s high-profile plight highlighted the challenges and helped inspire efforts to make the region a safer place to be a mountain lion — even if change hasn’t caught up to the heartbreaking reality.What’s billed as the largest wildlife crossing in the world — with a staggering price tag to match — is taking shape over a stretch of the 101 Freeway in Agoura Hills. A pair of bills that recently cleared the California Assembly would expand a ban on certain rodenticides and require cities to consider wildlife connectivity in planning documents.P-22 “did spur us to action,” Pratt said. The new mountain lion was spotted May 14 near Barham Boulevard. (Vladmir Polumiskov) Very little is known about the lion spotted in mid-May in a parking lot east of Barham Boulevard on the edge of roughly 4,200-acre Griffith Park.Vladimir Polumiskov captured video of the majestic creature on his phone after he and his wife and young son returned to their Hollywood Hills apartment after a weeknight dinner out. Headlights from Polumiskov’s car illuminate the cat’s sand-colored fur as he perches on a tree.Researchers who have seen the video believe it’s a young-leaning male lion. He’s not wearing a collar and therefore not part of the National Park Service’s 22-year study of mountain lions in and around the Santa Monica Mountains, of which Griffith Park marks the easternmost end. Scientists involved with the study are trying to find him — scouting primarily via remote cameras — so they can add him, said Seth Riley, a wildlife ecologist with NPS. If he’s captured and collared, scientists will be able to track his movements and analyze his DNA to see if he’s related to other lions in their database.Typically, young male mountain lions disperse, often traveling long distances to search for mates and a suitable home to call their own. That’s probably what P-22 was after — though he ended up in an abnormally small area for his species, and one believed to be lacking in lady lions. Experts didn’t expect him to stay long, but he hunkered down for 10 years.Griffith Park, surrounded on all sides by perilous freeways and roads, isn’t an easy place for a lion to get to — or leave. Pratt said the recently sighted lion probably hails from the Santa Monica Mountains and took the same harrowing trek as P-22, who presumably traversed the 405 and 101 freeways. But it remains speculation in the absence of a genetic workup.There’s no telling whether he’ll stick around.There are some upsides to the park. Namely, plenty of deer and no other adult male mountain lions, which chase and sometimes even fight young lions to the death.“He might not be in Griffith Park anymore,” said Pratt, California regional executive director for the NWF. “Or he could be settling in and claiming this for his new home.” A wildlife crossing over the 101 Freeway in Agoura Hills, pictured in an artist’s rendering, is expected to open in 2026. (RCD of the Santa Monica Mountains / Associated Press) Last month, Pratt scrawled “For P-22” onto the final girder placed onto the Wallis Annenberg Wildlife Crossing, a construction milestone that completed the bridge’s foundation. Numerous others honored P-22 in their own signatures, she said.Those who want to see Southland lions succeed point to the $92-million crossing as holding perhaps the biggest promise. If the crossing had been built when P-22 was looking to settle down, he might have been able to cross it and go north to “mountain lion paradise,” Los Padres National Forest, Pratt surmised.The 101 Freeway functions as an “impenetrable wall,” Pratt said. Lions to the south can’t get out and lions to the north can’t get in, forcing isolation and inbreeding. Birth defects, including kinked tails and deformed testicles, have already shown up in the small population sequestered in the Santa Monica Mountains. Next is likely sterility, Pratt said. A recent study found they could face extirpation within 50 years without intervention. Based on what researchers have learned, “this crossing will really be helpful for animals to leave the Santa Monicas, but also it’s kind of even more important, from a genetic point of view, that animals are able to come into the Santa Monicas,” said Riley, who is the branch chief for wildlife at the Santa Monica Mountains National Recreation Area and an adjunct professor at UCLA.“Because we’ve documented low genetic diversity in the Santa Monicas, and we’ve documented a bunch of cases of close inbreeding, where fathers are mating with daughters and close relatives are breeding.” The crossing is slated to open in 2026. And there’s a lot of work to be done before that to get it ready for animals on the move. Pratt said they’re currently working on the structure looming over a 10-lane stretch of freeway. Soon they’ll lay down two big slabs of concrete, and by the end of the year soil and plants will be added. Next spring, they expect to begin working on the portion over Agoura Road. Beth Pratt, pictured in 2021, said she and others are worried for the mountain lion recently spotted at the edge of Griffith Park. It’s not the most hospitable place for a big cat. (Gary Kazanjian / For The Times) Meanwhile, two bills that advanced out of the state Assembly last month aim to tackle mountain lions’ top challenges: cars, connectivity and rat poison. The bills, both introduced by Assemblymember Laura Friedman (D-Glendale), need to pass the Senate by Aug. 31 to land on the governor’s desk for final approval. Vehicle strikes are the top killers of mountain lions studied by the National Park Service. Rodenticides are tied for second with fights with other animals. P-22 was struck by a car toward the end of his life a few blocks south of Griffith Park and a subsequent exam revealed an old injury that may have been caused by another collision. He was also exposed to rat poison and developed mange. Assembly Bill 1889, called the Room to Roam Act, would require local governments to consider and implement measures to protect wildlife connectivity as part of their general plan. That could entail installing wildlife-friendly fencing or lighting or identifying and protecting a corridor known to be used by animals. (It does not require crossings to be built or land to be set aside.)The bill directs cities and counties to plan development in ways that don’t unnecessarily impact the movement of wildlife, said J.P. Rose, urban wildlands policy director at the Center for Biological Diversity, which sponsored the bill. Connectivity isn’t often considered until a specific development reaches the proposal stage, Rose said, which “misses a key opportunity to take a regional look at the issue of wildlife connectivity. And because it is a regional issue, the best place to look at it is in these kind of longer-term, broader plans.”The bill arrives about two years after the passage of a law that directed the California Department of Transportation to explore wildlife connectivity when it builds or expands roadways. The Room to Roam bill addresses the “other side of the coin,” Rose said. An Agoura Hills couple, whose home is near the in-progress wildlife crossing, captured a mountain lion on video outside their home in May. (Peggy McClintick and Sally Tuchman) Though previous laws have limited the use of certain rat poisons, others remain widely available. Assembly Bill 2552 would place restrictions on additional types, including removing them for over-the-counter purchase and limiting their use in wildlife areas.“This bill is an attempt to get some of those off the shelves so that people aren’t going to Home Depot and buying these super toxic rodenticides and unknowingly poisoning wildlife,” said Rose of the bill, also sponsored by the center.The poisons being targeted — chlorophacinone and warfarin — are known as first-generation anticoagulant rodenticides. They stop a rat’s blood from coagulating and stay in the animal’s system after it dies. When an unsuspecting mountain lion or owl gobbles a dead or sick rat — or another animal that ate a tainted rat — the toxic substance is passed on.Rose called the impacts “really heartbreaking.” He said poisoned predators don’t always die right away; sometimes they “slowly bleed to death from the inside.” The poisons can cause skin diseases and lead to organ failure and a depressed immune system, which might prevent animals from being able to find food or shelter in their sickened state — another pathway to death, he said.Riley, of the National Park Service, said researchers are “still continuing to get exposure in basically every animal we test.”His team believes it’s likely that the mountain lions they study are ingesting the poison when they eat carnivores — particularly coyotes, their second-most commonly consumed prey after deer. Often cougars go straight for their nutrient-rich organs, including the liver, where the compounds are stored. There’s general consensus that these efforts are part of a long game. No single crossing or law will be enough to make Southern California a safe place for mountain lions (or other wildlife). The goal is to continue building out connectivity while detoxifying the landscape — and make environmental and development decisions with the cats in mind going forward.Big cat supporters are already scheming about where to place future crossings.National Park Service researchers are conducting a connectivity study along a portion of the 101 Freeway at the western end of the Santa Monica Mountains known as the Conejo Grade. It’s an area with undeveloped land on both sides, Riley said. Recently, there were renewed calls for crossings north of San Diego County, where the 15 Freeway strands another population of genetically isolated lions. There have also been informal talks about where crossings could be installed in or near Griffith Park, according to Pratt. The Cahuenga Pass, where P-22 is believed to have crossed, is on their radar.If all goes well, P-22 might be the last of his kind.“If, in the long run, all of these areas were better connected, then animals, hopefully, in the future, won’t end up stuck in Griffith Park like P-22,” Riley said. Is the new mountain lion in Griffith Park? And for how long? (Brian van der Brug / Los Angeles Times )
