Amur leopard numbers have grown fivefold in Russia’s Far East

By / / Good News For Humankind

Amur leopard recovery has reached a milestone that conservation scientists once considered nearly impossible. Wild populations of the world’s rarest big cat have grown from roughly 25 individuals in the late 1990s to an estimated 130 in Russia’s Far East today, a fivefold increase driven by targeted habitat protection, anti-poaching patrols, and coordinated diplomacy between Russia and China. The 2012 creation of Land of the Leopard National Park — deliberately mapped around every known breeding territory — proved decisive in allowing both the leopards and their prey to rebound. Camera trap data confirming cross-border movement signals that the population is actively expanding rather than merely holding ground. Genetic fragility remains a serious concern, but this recovery stands as evidence that sustained, science-backed effort can reverse even catastrophic decline in large predators.

China tears out 300 dams on a Yangtze tributary to bring back endangered fish

By / / Good news links

Yangtze River restoration is advancing through one of the largest dam removal efforts in history, with China demolishing more than 300 dams and shutting down 342 small hydropower stations along the Chishui River. Critically endangered Yangtze sturgeon, a species that has survived for 140 million years, are already returning to previously blocked spawning grounds. Combined with a decade-long fishing ban imposed in 2020, the coordinated effort is producing measurable ecological recovery within years. The project adds significant momentum to a global dam removal movement and demonstrates that political will can reverse decades of river degradation at scale.

Global mercury emissions have fallen 70% since the 1980s

By / / Good News For Humankind

Mercury pollution has dropped 70% since 1982, marking one of the most significant environmental reversals in recorded history. Researchers confirmed the decline by analyzing mercury levels trapped in alpine plant leaves collected from the Tibetan Plateau near Mount Everest, revealing a clear link to global policy action and the worldwide shift away from coal. The UN’s Minamata Convention, adopted in 2013, and stricter emissions standards — including US regulations that cut American power plant emissions by roughly 90% — drove much of the progress. The achievement demonstrates that sustained international cooperation can reverse even deeply entrenched industrial pollution.

China becomes the first country to install 1 terawatt of solar power

By / / Good News For Humankind

China’s solar milestone reached one terawatt of installed photovoltaic capacity in 2025, making it the first nation in history to hit that mark, arriving ahead of schedule. The achievement is equivalent to 1.6 million utility-scale solar arrays running simultaneously and now represents half of all solar capacity installed worldwide as recently as 2024. Beyond climate goals, the buildout reflects a strategic push toward energy independence, reducing exposure to volatile fossil fuel markets. Most significantly, China’s manufacturing scale has driven global panel prices to historic lows, making clean energy newly affordable for developing nations that once had no realistic alternative.

China’s CO2 emissions fall for the first time as renewables surge past coal

By / / Good News For Humankind

China’s carbon dioxide emissions declined in 2024 for the first time on record, marking a potential turning point in the global fight against climate change. Driven by an extraordinary surge in wind and solar power, clean energy now generates more electricity in China than coal and gas combined. China alone installed roughly 300 gigawatts of new solar capacity last year, more than the entire United States has ever built. Because China accounts for nearly 30 percent of global CO2 emissions, this shift could accelerate worldwide emissions reductions years ahead of previous projections.

China sets new fusion endurance record of over a thousand seconds

By / / Good News For Humankind

Fusion energy took a real step forward this month: a reactor in China held superheated plasma stable for 1,066 seconds — more than 17 minutes, and over double the 403-second record the same machine set in 2023. The Experimental Advanced Superconducting Tokamak in Hefei pulled it off after engineers doubled the system’s power output while keeping the reaction from collapsing, which is the hardest part of fusion research. Sustained stability like this is exactly what a future fusion plant would need to actually generate continuous electricity. Findings from EAST will also feed directly into ITER, the massive international reactor rising in southern France. It’s a reminder that the dream of clean, nearly limitless energy is being built one patient breakthrough at a time.

China has reduced sulphur dioxide emissions by more than two-thirds in the last 15 years

By / / Good News For Humankind

China’s sulphur dioxide emissions fell by 70 percent between 2006 and 2017, even as the country’s economy roughly tripled in size over the same stretch. That kind of decoupling — slashing a major industrial pollutant while growing fast — is something climate scientists have long argued was possible but rarely seen at this scale. The shift came from real policy muscle: stricter enforcement, legal accountability for local officials, and a massive pivot to clean energy, with China funding nearly half of global renewable investment in 2017 alone. Coal still looms large and the work is far from done, but this milestone is tangible proof that entrenched pollution problems can move, and quickly, when commitment meets follow-through.

China completes historic 1,800-mile “Great Green Wall”

By / / Good News For Humankind

China’s Great Green Wall has helped lift forest cover from under 10% in 1949 to nearly a quarter of the country’s land today, across roughly 1,800 miles of arid north. In dunes near Hongshui village, 78-year-old farmer Wang Tianchang and his family have spent four decades planting sweetvetch shrubs in tidy squares — a technique locals call “holding down the sand” — alongside pines and blue spruces that now shield their fields. Tens of thousands of volunteers join each planting season, and species choices have grown sharper after decades of trial and error. The honest picture includes monoculture missteps and stubborn sandstorms, but Africa’s own Great Green Wall is drawing explicit inspiration — proof that patient, place-based restoration can ripple far beyond where the first seedlings go in.

China activates world’s largest offshore floating solar installation

By / / Good News For Humankind

Offshore floating solar just reached gigawatt scale: a fleet of 2,934 steel-truss platforms now sits eight kilometers off China’s Shandong coast, generating enough electricity each year to power roughly 2.6 million urban residents. Activated in November 2024, the Dongying farm is the largest installation of its kind ever built, anchored to withstand storms and saltwater in the Bohai Sea. Moving panels out to sea sidesteps the fierce competition for land that solar faces nearly everywhere, and the cooler ocean environment can actually help panels run more efficiently. As countries hunt for clean power without paving over farmland or forests, the ocean is starting to look less like an obstacle and more like the next great frontier.

Japanese researchers restore sight with stem-cell cornea transplants in a world first

By / / Good News For Humankind

Stem-cell cornea transplants have been successfully performed on human patients for the first time, with Japanese surgeons using reprogrammed induced pluripotent stem cells to restore vision in three of four participants — results that held for more than a year. Published in The Lancet in 2024, the trial offers a potential path around the global shortage of donor corneal tissue, which currently leaves millions without treatment options. Corneal disease is among the leading causes of blindness worldwide, making a scalable alternative to donor transplants significant. While the trial was small, a 75% sustained success rate in a first-in-human study is a meaningful early result.
