Along the sun-baked southern fringe of the Taklimakan Desert, China’s largest shifting sand desert, a sweeping, vibrant green barrier stretches far beyond the visible horizon. Hardy sand-fixing trees stand tall as resilient sentinels holding back encroaching dunes, while fruit orchards and medicinal plantations have taken firm root in what was once barren, inhospitable sand. This dramatic transformation is the result of the region’s ambitious Taklimakan Desert sand-blocking green belt initiative, which is delivering dual wins: reversing advancing desertification and unlocking new sustainable economic opportunity for local communities in southern Xinjiang, Northwest China.

What began as an ecological restoration project has evolved into a model of balanced development that pairs environmental protection with inclusive economic growth. Rather than treating desert management as a purely conservation effort, regional planners designed the green belt to support commercially viable, sand-adapted industries that benefit local households. Today, medicinal herbs such as Cistanche deserticola — a valuable traditional Chinese medicine — are grown among sand-fixing shrubs, while drought-tolerant fruit tree plantations produce high-quality crops for markets across China and beyond.

Official project data shows that the expansion of these sand-based sustainable industries now covers 10.83 million mu, equivalent to roughly 722,000 hectares, of former desert land. The sector generates an annual output value of 28.975 billion yuan, approximately $4.25 billion, injecting much-needed vitality into the regional economy and creating stable local jobs for rural residents. Photographs from mid-April 2026 captured workers at an agricultural technology firm in Aksu, a key prefecture along the desert’s edge, sorting processed slices of harvested Cistanche deserticola ahead of distribution to pharmaceutical and wellness markets.

Ecological monitoring data confirms the project’s environmental impact: the green belt has significantly slowed the southward advance of Taklimakan’s dunes, reduced regional sandstorm frequency, and improved overall soil retention across southern Xinjiang. For local stakeholders, the initiative stands as a proof of concept that arid desert landscapes do not have to be economic wastelands — with strategic planning and sustainable management, they can be turned into productive, vibrant lands that support both people and the planet.

Deep within the radioactive contamination of Ukraine’s Chernobyl Exclusion Zone, where humans have not been allowed to settle for nearly four decades, one of the planet’s most remarkable ecological recoveries is unfolding. On ground poisoned by the worst nuclear disaster in human history, rare and once-endangered wildlife roams free, turning a symbol of human catastrophe into an accidental wild refuge—now facing a new, man-made threat from Russia’s full-scale invasion of Ukraine.

The disaster that created this strange landscape dates back to April 26, 1986, when a catastrophic explosion at the Chernobyl Nuclear Power Plant blew a plume of radioactive fallout across much of Europe. The disaster forced the immediate evacuation of every town and village across a 2,600-square-kilometer exclusion zone spanning Ukraine and neighboring Belarus, displacing more than 100,000 people. To this day, the zone remains too radioactive for permanent human habitation, unfit for settlement for generations to come. But in the absence of people, nature has reclaimed the land.

Wolves now traverse the vast unoccupied terrain that humans abandoned. Brown bears, absent from the region for more than a century, have returned to repopulate their historic range. Populations of lynx, moose, red deer, and even free-roaming dog packs have rebounded dramatically, creating an ecosystem that mirrors the wild European landscapes of centuries past. The most notable success story, however, centers on Przewalski’s horse, a rare wild breed native to the steppes of Mongolia that once hovered on the edge of total extinction.

Distinct from all domestic horse breeds, Przewalski’s horses carry 33 pairs of chromosomes—one more than their domesticated relatives— and are the last truly wild horse species walking the planet today. Known as takhi, meaning “spirit,” in their native Mongolia, the species was first formally documented by 19th-century Russian explorer Nikolai Przhevalsky, from whom it takes its common name. As the species declined to near-extinction across its original Asian range, conservationists launched an experimental reintroduction in the Chernobyl exclusion zone in 1998, releasing a small founding population into the radioactive landscape.

Four decades on, that experiment has yielded what leading zone ecologist Denys Vyshnevskyi calls a “small miracle”: a self-sustaining, free-roaming population of the rare horses has taken root and grown. Hidden motion-activated camera traps, which Vyshnevskyi spends hours installing across dense, overgrown terrain, have revealed the horses adapting to their new home in unexpected ways: they seek shelter from harsh winters and biting insects in crumbling Soviet-era barns and abandoned human homes, even bedding down inside the derelict structures. While many of the original introduced animals died off in the first years, the remaining population has adapted, forming small, stable social groups: one mature stallion, multiple mares, and their young, alongside separate all-male bands of younger horses.

Scientists have not recorded widespread wildlife die-offs tied to the zone’s persistent background radiation, though subtle biological impacts have been documented: some frog species have evolved darker pigmentation to protect against radiation damage, while bird populations in the most contaminated areas show higher rates of cataract development. Even so, ecologists broadly agree that the absence of human activity, from industrial development to hunting and agriculture, has created a net benefit for wildlife that far outweighs the costs of low-level radiation exposure. “Nature recovers relatively quickly and effectively,” Vyshnevskyi explained, noting that the exclusion zone now looks much like European landscapes did centuries before widespread industrialization and human settlement. The transformation is visible to the naked eye: tree saplings push through the foundations of abandoned apartment blocks, crumbling roads have been reclaimed by forest, and faded Soviet road signs stand weathered beside overgrown cemeteries dotted with leaning wooden crosses.

For conservation science, the Chernobyl recovery offers an unprecedented natural experiment. “For those of us in conservation and ecology, it’s kind of a wonder,” Vyshnevskyi said. “This land was once heavily used—agriculture, cities, infrastructure. But nature has effectively performed a factory reset.”

That accidental wonder is now under severe threat from the 2022 Russian invasion of Ukraine. When Russian troops advanced toward Kyiv in the early weeks of the war, fighting swept directly through the Chernobyl exclusion zone, with soldiers digging fortifications and military positions directly into contaminated soil. Military activity has sparked widespread wildfires across the zone’s forests, sparked by downed drones and artillery strikes. Oleksandr Polischuk, who leads a local firefighting unit in the zone, says crews often must travel dozens of kilometers across unpaved, dangerous terrain to reach blazes. The fires pose an additional hidden risk: they can stir up trapped radioactive particles and release them back into the atmosphere, spreading contamination across wider areas.

Harsh wartime winters and damage to Ukraine’s power grid have also taken a heavy toll, stripping protected area management teams of critical resources. Scientists have recorded sharp increases in fallen trees and dead wildlife, casualties of both extreme cold and hastily built military fortifications that fragment habitat and disrupt animal movement. Today, the exclusion zone is no longer just a quiet accidental wildlife refuge: it is a heavily militarized corridor, crisscrossed with concrete barriers, barbed wire, and unmarked minefields. Personnel who monitor the wildlife and maintain the zone rotate in and out constantly to limit their radiation exposure, just as they navigate the constant risks of a war that has settled across the contaminated landscape.

The paradox of Chernobyl remains, decades after the disaster: it will almost certainly remain off-limits to permanent human settlement for generations. It is a landscape defined by one of humanity’s worst mistakes, too dangerous for people to call home. Yet in that absence, it has become a haven for life—one that ecologists are working desperately to protect even amid the chaos of a new man-made conflict.

A groundbreaking new audit released Thursday has exposed large-scale noncompliance with China’s national policy to cut unnecessary single-use plastic waste in the hospitality sector, revealing that star-rated hotels — the first establishments required to phase out routine provision of disposable plastic amenities — are falling even further behind their non-star-rated counterparts in meeting regulatory requirements.

The investigation was jointly conducted by two leading Chinese environmental nonprofits: the Institute of Public and Environmental Affairs (IPE) and the Wuhu Ecology Center, with technical and strategic guidance from the China Forum of Environmental Journalists. The research combined nationwide public oversight activities with on-the-ground field surveys to paint a comprehensive picture of policy adherence across China’s accommodation industry.

The policy in question was first rolled out by China’s Ministry of Commerce in August 2020, as part of the country’s broader national strategy to curb growing plastic pollution. The phased rule mandated that all star-rated hotels end the proactive placement of disposable plastic toiletries and amenities in guest rooms by the end of 2022, with the requirement expanding to all hotels, guest houses, and homestays nationwide by the end of 2025.

Despite this clear five-year phase-in period for the first phase of the mandate, the 2025 public monitoring initiative led by IPE and its partner NGOs confirms that the vast majority of hotels across China continue to automatically place disposable plastic toothbrushes, combs, and other single-use amenities in guest rooms without request.

The hotel plastic reduction monitoring project, which collects real-time, photo-verified data from volunteer observers across the country, had expanded to cover 1,867 hotels across 256 Chinese cities by the close of 2025. Of these surveyed locations, only 8.4 percent have stopped proactively placing disposable toothbrushes, and just 12.1 percent have ended routine provision of disposable plastic combs.

Most alarmingly, the report classifies star-rated hotels — which were given a two-year head start to comply with the rule — as the most consistent “laggards” in the sector. Every single one of the 40 five-star hotels included in the survey was found to still automatically provide full sets of disposable plastic amenities to guests. Further, data confirms that the share of compliant star-rated hotels for both disposable toothbrushes and combs is lower than the corresponding compliance rate among unrated accommodation establishments.

Ma Jun, founding director of IPE, outlined two core barriers driving widespread noncompliance among high-end and star-rated properties. First, a long-standing industry norm in China ties the perceived quality of hotel service directly to the inclusion of free disposable amenities, creating a cultural expectation that operators are reluctant to challenge. High-end hotels’ core customer base, which includes a large share of frequent business travelers, tends to prioritize granular service details, and intense market competition has left most properties fearful that becoming an early adopter of plastic reduction would harm customer satisfaction and put them at a competitive disadvantage against peers that continue to offer disposables.

Second, Ma noted that current regulatory frameworks impose only weak enforcement constraints on star-rated and high-end hotels. While 16 Chinese cities have introduced formal financial penalties for hotels that continue proactively providing prohibited disposable plastics, only 280 penalty cases were recorded across these jurisdictions between 2019 and 2025. And nearly all of these penalties were issued to small and medium-sized non-star-rated hotels, with almost no enforcement action taken against high-end star-rated properties.

Compounding these issues, Ma added that plastic waste reduction carries very little weight in China’s official hotel star-rating assessment framework and national green hotel certification programs, removing a key incentive for properties to invest in compliance.

Industry data underscores the scale of the plastic waste problem the policy is intended to address. According to the China Hospitality Association, China was home to more than 570,000 separate accommodation facilities and over 19 million guest rooms as of the end of 2024. A 2025 industry report estimated that China’s accommodation sector consumed 73,000 metric tons of disposable plastic products in 2020 alone, a figure that has remained largely steady due to widespread noncompliance with the reduction rule.

Tucked away in the remote eastern reaches of Indonesia, the Raja Ampat archipelago rises from the Coral Triangle, the global epicenter of marine biodiversity. Powerful, nutrient-rich ocean currents course through its waters, nurturing a kaleidoscopic underwater landscape where sharks, manta rays, and sea turtles glide past ancient sea fan corals—some found nowhere else on the planet. No other place on Earth concentrates such a staggering volume of marine life into such a compact area, according to Mark Erdmann, an American coral reef biologist who has dedicated more than 20 years to studying the region and shaping its landmark conservation framework. Holding 75% of the world’s documented hard coral species and over 1,700 fish species, Raja Ampat is widely recognized as one of the most critical ocean ecosystems on the planet, but its decades-long conservation success is now under growing threat from two overlapping forces: the global push for renewable energy that is driving nickel mining expansion and a post-pandemic surge in international diving tourism.

The archipelago’s journey to conservation success was not always smooth. At the turn of the 21st century, unregulated overfishing by outside fleets left the ecosystem in tatters: fishermen used explosive devices and giant gill nets that shattered fragile coral colonies and decimated local shark populations, forcing native fishing households to travel up to 10 kilometers offshore just to bring in a viable catch. At the time, the regional government relied almost entirely on extractive industries—mining and logging—as its core economic drivers, leaving the reefs with little formal protection. The turning point came when a 2003 marine assessment conducted by Conservation International opened up critical dialogue between local government leaders, Indigenous communities, and environmental groups, centered on one core question: could protecting Raja Ampat’s natural assets deliver more long-term food security and sustained economic revenue than continued extraction? To demonstrate the potential of conservation, conservation organizers brought regional leaders to established ecotourism destinations like Bali and Bunaken, letting them see first-hand the economic and social benefits of thoughtful natural resource management.

Those conversations laid the foundation for a transformative conservation model: by 2007, 10 distinct marine protected areas had been established across Raja Ampat, covering 2 million hectares—roughly 45% of the archipelago’s total reef, seagrass, and mangrove habitats. Today, local community members patrol the protected waters, enforce sustainable fishing rules, and monitor tourism activity, with most operational funding coming directly from tourism revenue, including a $40 entry fee for all international marine park visitors. After 20 years of consistent protection, the results are unprecedented: a 2024 assessment from the Misool Foundation recorded a 109% increase in fish biomass, the key metric for measuring marine ecosystem health, and the archipelago now hosts a stable population of 2,007 documented reef manta rays—a remarkable number for a species classified as vulnerable to extinction across most of the Indo-Pacific.

This conservation success has coincided with the global transition to renewable energy, which has sent demand for nickel soaring. Nickel is a core component of electric vehicle batteries and critical for wind and solar energy infrastructure, and Indonesia controls roughly 43% of the world’s total nickel reserves, making the metal central to the country’s national economic development strategy. In 2025, the Indonesian government granted new nickel mining concessions on three northern islands in Raja Ampat, some located within a designated UNESCO Global Geopark and just kilometers from the archipelago’s most popular diving sites. Public outcry over the concessions led the government to revoke four permits, but one active concession remains on Gag Island, where mining operations first launched in 2017.

Environmental activists warn that the damage from mining is already accumulating, with no clear plan for remediation. “The heavy machinery, excavators, bulldozers—they’re still there (in the islands),” explained Timon Manurung, director of Indonesian environmental advocacy group Auriga Nusantara, adding that no party has taken responsibility for restoring land and waters already degraded by mining activity. The archipelago’s steep terrain and heavy annual rainfall amplify the environmental risk: sediment eroded from cleared mining sites flows directly into nearshore waters, smothering corals and blocking the sunlight they need to survive. “In the end, it will cause coral reefs to die,” said Syafri Tuharea, head of the Raja Ampat Marine Conservation Area. The active mining zone also lies along a critical migration corridor for reef manta rays, the archipelago’s biggest international tourism draw. Beyond its coral reefs, Raja Ampat holds extensive seagrass meadows and mangrove forests—coastal ecosystems that act as some of the world’s most powerful natural carbon sinks, absorbing far more carbon dioxide per hectare than terrestrial forests. A 2026 study from Auriga Nusantara found that mining-related deforestation has already cleared nearly 1,000 hectares of coastal and island habitat, an area Manurung calls significant for the archipelago’s small, fragile landmasses.

Alongside mining pressure, a shifting profile of tourism is placing new strain on the ecosystem. Annual visitor numbers have held steady over the past decade, but the share of international tourists has surged to 95% of the roughly 42,000 annual visitors, while domestic tourism has dropped by more than two-thirds. Most international visitors come for week-long liveaboard diving expeditions, and the number of these vessels has grown rapidly over the past 10 years, according to Kristanto Umbu Kudu, a local dive guide with 25 years of experience working in Raja Ampat. Conservation leaders say the increase in liveaboard traffic has led to widespread coral damage from ship anchors, plus growing volumes of untreated waste and sewage discharged into protected waters. “Our data shows that in 2024, there were 218 tourist ships,” Tuharea said. “Can you imagine how many square meters of coral reef will be destroyed because of the anchors?” Regional authorities are currently discussing the introduction of designated mooring systems and caps on the number of tourist vessels allowed in protected waters, but regulations have not yet been finalized. Even at popular dive sites, visible signs of pollution are growing: at Blue Magic, one of the archipelago’s most iconic dive spots, crystal-clear waters that once drew divers from around the world are now often littered with floating plastic waste, tangled around jellyfish and drifting past reef formations. “That’s something which still breaks my heart every time I see these big rafts of floating plastic,” Erdmann said.

For marine scientists and divers alike, what is at stake extends far beyond the popularity of Raja Ampat as a diving destination. “It is one of the few places in the world, alongside the Amazon, where biodiversity actually increases from year to year,” said Pol Ramos, a Spanish marine biologist and co-founder of Odicean, a non-profit that combines ocean education with research dive expeditions in the region. Beyond the sheer number of species, Raja Ampat holds irreplaceable genetic diversity: every species in its waters carries millions of years of evolutionary adaptation encoded in its DNA, a natural library of solutions that Erdmann says will be critical as the planet adapts to accelerating climate change. “As we go into a more and more uncertain future with climate change,” Erdmann said, “it’s that genetic diversity that’s what we have to work with in terms of how we adapt.”
