Salmon return to Klamath River for first time in 112 years

By / / Good News For Humankind

Wild Chinook salmon have returned to the upper Klamath River for the first time since 1912, with biologists confirming the fish about 230 miles inland from the Pacific. The sighting came just months after the last of four dams was removed in summer 2024, completing the largest dam removal project in U.S. history. Klamath tribal members, who fought for decades to free the river, describe the salmon’s return as the homecoming of relatives. Biologists hope steelhead, coho, Pacific lamprey, and bull trout will follow. For rivers everywhere still bound by aging dams, one fish swimming home is a reminder that ecosystems can begin healing the moment we let them.

Chase Strangio to be the first openly trans lawyer to present to the Supreme Court

By / / Good News For Humankind

Chase Strangio made history on December 4, 2024, becoming the first openly transgender lawyer to argue before the U.S. Supreme Court. The case, U.S. v. Skrmetti, challenges Tennessee’s ban on gender-affirming care for trans minors — and Strangio came prepared, having argued the core issues before federal appeals courts four times, more than any attorney in the country. His path here runs through Obergefell, Bostock, and a winning challenge to Arkansas’s youth healthcare ban, alongside grassroots work supporting LGBTQ+ immigrants. Whatever the Court decides, the moment itself matters: trans communities, so often the subject of legal disputes rather than participants in them, finally had one of their own at the lectern — a shift in who gets to shape the law that shapes their lives.

California gets final approval for nation’s third-largest marine sanctuary

By / / Good News For Humankind

Chumash Heritage National Marine Sanctuary now protects 4,543 square miles of California coastline, making it the country’s third-largest marine sanctuary and the first anywhere in the U.S. shaped from the start by Indigenous tribes. The waters off San Luis Obispo and Santa Barbara counties are so biologically rich that one Chumash leader compares them to the Galápagos, and they’re now off-limits to oil and gas exploration. The designation also safeguards ancient village sites resting on seafloor that was dry land thousands of years ago. After a decade of tribal-led advocacy, this sanctuary offers a new model for ocean conservation — one where the people with the longest relationship to a place help decide its future.

U.S. announces 10-year deadline to remove all lead pipes nationwide

By / / Good News For Humankind

Lead pipes in roughly nine million American homes are now on a federal clock: the EPA’s new rule requires every utility to find and replace them within 10 years. Backed by $2.6 billion in fresh funding, the policy marks a dramatic shift from previous timelines that stretched 40 or even 50 years out. Nearly half the money is directed to disadvantaged communities, where decades of disinvestment left lead lines in place long after wealthier neighborhoods got upgrades. Milwaukee mother and advocate Deanna Branch, whose son was poisoned by lead, said the shorter timeline finally gives her hope she’ll live to see the pipes pulled from her city. For a country where clean water has long depended on your zip code, a hard deadline is itself a milestone.

Virus up close, for article on lenacapavir HIV prevention

‘Gamechanger’ HIV prevention drug to be made available cheaply in 120 countries

By / / Good News For Humankind

Lenacapavir, a twice-yearly HIV prevention shot with near-perfect results in clinical trials, is about to become far more affordable for millions of people. Gilead Sciences has licensed six generic manufacturers across India, Egypt, Pakistan, and the U.S. to produce the drug for 120 lower-income countries, where researchers estimate it could eventually be made for as little as $40 per patient per year. In trials among cisgender women in South Africa and Uganda, not a single participant who received the injection contracted HIV. Advocates are urging wider access, since much of Latin America was left out of the deal. Still, it’s a hopeful signal that breakthrough prevention tools can reach the people who need them most — fast.

World Health Organization approves first mpox diagnostic test for emergency use

By / / Good News For Humankind

The first mpox diagnostic test has been cleared through the World Health Organization’s Emergency Use Listing, opening a faster procurement route for the countries hit hardest by the outbreak. Abbott’s Alinity m MPXV assay detects both clades of the virus from rash samples, and UN agencies can now order it directly for places where national approval pathways would otherwise take months. That speed matters: in 2024, only 37% of suspected mpox cases in the Democratic Republic of the Congo were confirmed by testing, leaving outbreaks harder to trace. Three more tests are already under WHO review, with more manufacturers in talks. It’s a hopeful signal that the world is learning from past pandemics — building diverse, quality-assured tools before bottlenecks become catastrophes.

Claudia Sheinbaum is sworn in as Mexico’s first female president

By / / Good News For Humankind

Claudia Sheinbaum won Mexico’s presidency with roughly 59% of the vote in June 2024 — the largest margin in the country’s modern democratic era — and took office as the first woman and first Jewish person to lead the nation of 130 million. A climate scientist with a doctorate in energy engineering, she contributed to landmark IPCC reports before entering politics, and as Mexico City’s environment secretary she helped launch the Metrobús system that reshaped how millions get around. In her first months in office, she used a legislative supermajority to write universal healthcare and inflation-beating minimum wage protections directly into the constitution. Her rise signals that scientific expertise and bold social reform can sit at the very center of democratic leadership.

California tears down levee in ‘largest tidal habitat restoration in state history’

By / / Good News For Humankind

Tidal waters rushed across 3,400 acres of California’s Sacramento-San Joaquin Delta this month after crews cut a 600-foot gap through a century-old levee at Lookout Slough — the first of nine planned breaches in what’s being called the largest tidal habitat restoration in state history. The reborn marsh will offer shallow, sediment-rich water for the endangered Delta smelt, a tiny fish whose health signals the wellbeing of the entire food web, while also giving salmon better passage and migrating birds new resting ground. It will also hold more than 40,000 acre-feet of floodwater, easing pressure on Sacramento-area communities during heavy storms. Lookout Slough is a quiet reminder that working with natural water systems, rather than against them, can protect wildlife and people at once.

California bans all plastic shopping bags at grocery stores

By / / Good News For Humankind

California’s plastic bag ban gets real on January 1, 2026, when even the thicker “reusable” plastic bags that quietly replaced the originals will disappear from grocery stores, pharmacies, and convenience stores statewide. Senator Catherine Blakespear, who authored the bill, put it plainly: those bags were single-use in everything but name. Shoppers will reach for paper or bring their own, and families using CalFresh and similar food assistance won’t pay the paper bag fee. California’s market is huge enough that what happens at its checkout counters tends to ripple outward, nudging manufacturers and other states to rethink their own rules. It’s a small, tangible reminder that closing loopholes — not just passing laws — is where real progress lives.

Governor bans use of ‘conversion therapy’ on LGBTQ+ minors in Kentucky

By / / Good News For Humankind

Kentucky’s conversion therapy ban, signed by Gov. Andy Beshear this week, takes effect immediately and protects every minor seeing a licensed mental health professional in the state. The order also blocks state and federal dollars from funding the practice and lets licensing boards discipline anyone who violates it. One survivor at the signing, filmmaker Zach Meiners, spoke about four years of sessions as a teenager that he’s “still unraveling” — a reminder of why major medical groups have long called the practice harmful. Kentucky now joins nearly half of U.S. states with similar protections, a quietly growing patchwork that’s reshaping what safety looks like for LGBTQ+ young people even as other fights continue.
