No, this isn't a promo for the latest season of The Last of Us — it's a map of U.S. rivers and streams contaminated with harmful levels of the pesticide atrazine.

This hormone-disrupting, cancer-linked chemical is the United States’ most widespread pesticide water pollutant. It's so dangerous it's been banned in more than 60 countries.

Yet the EPA wants to reapprove its use — without legally required water-quality standards — for another two decades.

So last week, the Center and our allies filed a lawsuit to make the Trump administration’s Environmental Protection Agency set water-pollution limits for atrazine.

We're also working to ban atrazine for good.

If you haven’t yet, sign our petition asking the agency to ban atrazine once and for all. ➡️ https://bit.ly/4eH4gAw

Just when you thought data centers couldn't cause more trouble than they already are: An underwater AI data center could be coming to Cook Inlet, Alaska.

A preliminary permit application for the proposed data center is being considered by the Federal Energy Regulatory Commission.

Up to 1,650 acres of marine habitat could be developed with hundreds of tidal turbines and server hubs — right in the heart of critical habitat for endangered Cook Inlet beluga whales.

Beluga whales rely on sound for almost every aspect of their lives and they're exceptionally sensitive to underwater noise and development.

The vessel traffic and underwater surveying just from the proposed studies — not to mention the actual data center development — would threaten the survival of these critically imperiled whales.

Don't let Cook Inlet belugas become the latest casualty of the data center boom.

Please take a moment to urge the commission to deny this preliminary permit application. Please speak up at ➡️ https://bit.ly/3SP8tKZ

Our annual Food Justice Film Festival is back!

Join us for free Oct. 22-25 to watch four award-winning documentaries that highlight Indigenous seed sharing, food sovereignty, cultural heritage, and the importance of shifting toward agroecological farming.

This year’s lineup:
• Seeds of Sovereignty spotlights Mexico’s effort to protect itself from the U.S. push for GMO corn and other industrial farming practices.

• Seeding Change: Farming Beyond Neonics explores what the U.S. Northeast’s future would look like if seeds weren’t treated with neurotoxic insecticides called neonicotinoids.

• Toxic Harvest: The Hidden Truth About Pesticides (Rosa Luxemburg Foundation) uncovers agricultural pesticides’ devastating impacts on South Africa.

• Seed Is Life (African Centre for Biodiversity) explores South Africa and Zimbabwe’s fight to protect their cultural heritage and reclaim the rights to their seed.

Watch this incredible lineup of award-winning films as well as interviews with filmmakers, farmers, organizers, and activists.

The North Atlantic right whale is one of the world’s most endangered whales — fewer than 400 individuals remain.

Once common along the eastern U.S. seaboard, the whale was hunted to near-extinction by the 1750s.

While no longer pursued for its oil, meat and bones, these whales continue to be the victim of ship strikes and entanglement in fishing gear, which can result in protracted, painful deaths.

Tragically, these whales are declining so quickly that they may be functionally extinct by 2040 if more isn’t done to save them.

There's one thing you can do right now to help them out: Help stop an underwater AI data center from being built in their habitat.

Right now the Federal Energy Regulatory Commission is considering a preliminary permit application to build an underwater AI data center off the coast of Maine.

The proposed project would span at least 27 acres within the Bay of Fundy — a vital feeding area, nursery, and migratory corridor for critically endangered North Atlantic right whales.

Join us in urging the commission to reject this preliminary permit application. We only have until Oct 19 to speak up. Submit your public comment at 🐋➡️ https://bit.ly/4ioAGSE

In a dangerous series of rollbacks, the Endangered Species Act has suffered blow after blow. These devastating attacks affect the plants and animals that depend upon this vital law to survive.

Most recently, Congress has introduced a “permitting reform” to weaken Endangered Species Act review and remove safeguards for threatened and endangered wildlife like polar bears, manatees, sea turtles and hundreds of other species. If this moves forward, the lives of countless species are at risk.

Attacks like these are pushing already numbered species to the brink of extinction. We must save the Endangered Species Act from death by a thousand cuts. It’s not too late to stop this bill from passing.

Tragic news: According to a Botswana news outlet, trophy hunters killed two satellite-collared elephants in the country, one on Sept. 3 and the other on Sept. 4.

Researchers were studying these elephants for better insight on their migratory patterns and habitat use.

Now the animals — and the science they supported — are gone.

A 2026 case study by the Center for Biological Diversity found that U.S. trophy hunters frequent Botswana. If the hunters who killed these precious collared elephants are from the United States, they shouldn't be allowed to bring any part of the animals back to the country with them.

You can help speak up for elephants by urging leaders from the U.S. Department of the Interior and Fish and Wildlife Service to act.

Tell them to deny import permits for these elephants and protect elephants by banning all elephant trophy imports from Botswana. ➡️ https://bit.ly/4dz5zkH

7 Major Reasons to Celebrate: The Center for Biological Diversity has been fighting hard for public lands this year, and, with the help of our many allies and supporters, we’ve have secured amazing, historic wins all throughout the country.

From Alaska to Florida and everywhere in between, the Center will continue to stand between wanton destruction and our cherished ecosystems. Stay tuned for more wins as the battle for our public lands heats up. If there is a challenge, we’ll be there.

Because this is a world worth fighting for.

Support our work and join the fight to protect public lands in any way that you can: https://biodiv.us/4zD6fy5

The Endangered Species Act is under attack yet again — and we need everyone to join us in speaking up to defend it right now.

Congress recently introduced a permitting reform package: The Bipartisan American Affordability and Jobs Act of 2026.

It's under the guise of helping renewable energy, but it's really a massive giveaway to the fossil fuel industry with a backroom deal that guts the Endangered Species Act.

The legislation cuts the Act's “best available science” mandate by making it all but impossible for scientists to prove that imperiled species and the places they live need protection.

Among several other concerns, it would also surrender one of the Act's most important safeguards — the requirement for federal oversight of wildlife decisions — to hostile state agencies.

We don’t have to choose between protecting our most endangered animals and plants and building a clean energy future.

We only have a short window to stop this so please contact your senators right now and urge them to reject this bill and protect the Endangered Species Act. ➡️ https://bit.ly/3VpJa34

Today we honor Indigenous Peoples of this land and mourn the painful history and continued injustice against Native Americans.

As today is a day of reflection, the Center for Biological Diversity celebrates the profound knowledge, wisdom, and culture of Indigenous communities that we continue to learn from.

We reiterate our commitment to working with Native American Tribes and Indigenous communities to fiercely protect our lands, wildlife, water, and planet and to fight environmental racism and colonialism.
