Peru approves the creation of long-awaited marine protected area

By / / Good News For Humankind

Peru’s new Grau Tropical Sea National Reserve safeguards 115,675 hectares of ocean where the warm Eastern Pacific meets the cold Humboldt Current — a collision the IUCN ranks among the 70 most vital places on Earth for marine biodiversity. Humpback whales birth their calves here, hammerhead sharks patrol the reefs, and scientists keep finding species entirely new to them. The reserve also matters for people: of the 35 main fish species landed by Peru’s artisanal fleet, 24 come from these waters. Created after more than a decade of advocacy by fishers and scientists, the designation is a real step toward the global goal of protecting 30% of the ocean by 2030 — and a reminder that lasting protection still depends on enforcement and political will.

Campesinos plant nearly a million trees in deforestation hotspot in the Colombian Amazon

By / / Good News For Humankind

More than 700 campesino families in the Colombian Amazon have planted nearly a million native trees across former cattle pasture, transforming one of the country’s worst deforestation hotspots into recovering forest. In just four months, families across the Cuemaní region planted over 984,000 trees and palms — and tapirs, deer, and parrots that had disappeared with the chainsaws are already coming back. Teenagers who joined botanical surveys alongside scientists discovered they could earn a living as local forest experts, with some now pursuing degrees in agroforestry. What makes this remarkable isn’t just the scale, but the model: when the people who once cleared the land become its protectors, restoration starts to hold — a lesson echoing across the Amazon and beyond.

Whale tail, for article on sei whale return

Sei whales reappear in Argentine waters after nearly 100 years

By / / Good News For Humankind

Sei whales are back in Argentina’s coastal waters for the first time in roughly 100 years, after industrial whaling wiped them out in the 1920s and 30s. These blue-grey giants are the third-largest whales on Earth and among the fastest, which once made them prime targets for hunters. Their slow return — the species reproduces just once every two or three years — is a quiet testament to the 1946 international whaling treaty that gave them room to rebuild. Global numbers now sit around 50,000 and are trending upward, though sei whales remain endangered. Their reappearance off Patagonia carries a hopeful lesson for marine conservation everywhere: give a species enough time and enough protection, and it can find its way home.

Brazil takes pioneering action to rewild howler monkeys

By / / Good News For Humankind

Brazil has launched its first national population management program for the brown howler monkey, a species now ranked among the 25 most threatened primates on Earth after yellow fever outbreaks killed thousands. Coordinated across eight states, the program pairs a newly adapted yellow fever vaccine with strategic translocations to restore wild populations. In Rio de Janeiro’s Tijuca National Park, two groups of howlers now live in an urban forest where the species had been absent for over a century. The effort offers a potential model for other imperiled Atlantic Forest species.

Seven countries now generate 100% of their electricity from renewable energy

By / / Good News For Humankind

Renewable energy now powers more than 99.7% of electricity in seven countries: Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia, and the Democratic Republic of Congo. Each one leaned into what their landscape offered — Himalayan rivers, volcanic heat, massive shared dams — and built their grids around it. They’re the leading edge of a wider shift, with roughly 40 countries now sourcing at least half their electricity from renewables. Stanford’s Mark Jacobson puts it plainly: no miracle technologies are needed, just focused deployment of wind, water, and solar. These seven nations are quiet proof that a modern society running on clean power isn’t a distant goal — it’s already happening, and the rest of the world is catching up.

Brazil boosts protection of Amazon mangroves with new reserves in Pará state

By / / Good News For Humankind

Brazil has protected nearly all of Pará state’s Amazon coastline after President Lula signed a decree creating two new extractive reserves — the Filhos do Mangue and the Viriandeua — adding 74,700 hectares of mangrove ecosystems to federal protection. The move completes what experts call the world’s largest and most conserved mangrove belt, securing the livelihoods of roughly 7,100 families and locking away massive stores of carbon. It took 16 years of community organizing to make it happen. 83 words.

In first, an Argentine court convicts ex-officers of crimes against trans women during dictatorship

By / / Good News For Humankind

Argentina just made legal history: a court in La Plata convicted 11 former officials of the 1976–1983 dictatorship for crimes against humanity specifically committed against transgender women — believed to be the first ruling of its kind anywhere in the world. Eight trans plaintiffs took the stand to testify about rape and torture at the Banfield Pit, one of the country’s largest clandestine detention centers. Ten defendants received life sentences; one was sentenced to 25 years. When the verdict was read, survivors and families packed the courtroom and wept. Argentina has been quietly building the world’s most ambitious reckoning with state terror, and this ruling extends that work to a community long left outside official memory — a model other nations are studying.

Bolivian rainforest, for article on Amazon rainforest protection

Bolivian town Sena protects 1 million acres of Amazon rainforest

By / / Good News For Humankind

Amazon rainforest protection just got a remarkable boost from an unlikely source: a Bolivian town of 2,500 people passed a law safeguarding 1.1 million acres of intact forest. The new Gran Manupare reserve lifts conservation coverage in Bolivia’s Pando Department to 26% of its land, and locks in an estimated 9.2 million tons of irrecoverable carbon. It’s also a haven for giant river otters, jaguars, and big-leaf mahogany — and it works because standing forests pay, thanks to a Brazil nut economy that depends on healthy ecosystems. Piece by piece, Bolivian communities have now stitched together 10 million contiguous hectares of protected Amazon, proving that community-led conservation can match anything achieved by national decree.

New fund supports Indigenous-led land management in biodiverse area of Bolivia

By / / Good News For Humankind

Indigenous communities in Bolivia’s Madidi Landscape just launched a dedicated conservation fund, opening with $650,000 from the Bezos Earth Fund to back work they’ve been doing for generations. Four nations — the Tacana, Lecos, T’simane Mosetene, and San José de Uchupiamonas — will direct the money themselves through an Indigenous-led board, finally putting resources behind territorial plans they first drafted twenty years ago. Madidi National Park is the most biodiverse protected area on land anywhere, home to more than 9,000 recorded species, from Andean condors to maned wolves. Globally, only a sliver of conservation funding reaches Indigenous hands directly, even though these communities steward most of the world’s remaining biodiversity. Funds like this one offer a hopeful blueprint for changing that.

River dolphin, for article on river dolphin declaration

11 countries sign global pact to protect endangered river dolphins

By / / Good News For Humankind

River dolphins just got their first global lifeline: 11 countries have signed the Global Declaration for River Dolphins, a pact aiming to double Asian populations and halt declines across South America by 2030. It’s a meaningful turn for a group of species that has lost nearly three-quarters of its numbers since the 1980s. The hope isn’t abstract — China’s Yangtze finless porpoise population grew 23% over five years under strict protections, and the Indus river dolphin has nearly doubled in two decades. Because dolphins signal the health of the rivers nearly a billion people depend on, their recovery points toward something larger: that coordinated, community-rooted conservation can still pull ecosystems back from the brink.
