Let's start this week off with a WIN!

Rusty patched bumblebees were just granted 1.57 million acres of critical habitat. This designation was just finalized on Friday by the U.S. Fish and Wildlife Service and secures protection for places essential to the survival of one of America’s most imperiled pollinators.

This win is the result of a lawsuit we filed alongside our allies NRDC and Friends of Minnesota Scientific and Natural Areas, which challenged the Service's earlier decision to deny critical habitat for the imperiled species.

Once common across the eastern and midwestern United States, the rusty patched bumblebee has already disappeared from nearly 90% of the places it once lived.

You simply cannot protect a species without protecting the places they live. This critical habitat designation will help give these fuzzy pollinators a chance to survive.

You know it’s been a busy week when the update includes lawsuits over horseshoe crabs, coral reefs, cancer-linked pesticides, and air pollution in the Everglades.

Every week, the Center is in courtrooms, agencies, and communities across the country fighting for wildlife, clean water, public health, and wild places. These are just a few of the stories that shaped this week.

Watch the update, follow for more, and join our broadcast channel for the full weekly round up.

If you've ever visited the Atlantic coast, you may have been lucky enough to see living fossils — horseshoe crabs.

And if you're a frequent beachgoer, you may have noticed fewer and fewer of these ancient creatures dotting shorelines, if you even see them at all anymore.

Horseshoe crab populations have plummeted by more than 70% in recent decades due to overharvesting and habitat loss.

These creatures, nearly twice as old as dinosaurs, have survived meteor impacts and ice ages but they’re facing their biggest threat yet: humans.

As horseshoe crabs have declined, so have other species that feed on them, like endangered sea turtles and shorebirds.

Despite their massive population decline, the Trump administration has denied horseshoe crabs protections under the Endangered Species Act.

So today, we sued the administration over that decision.

We're not going to let horseshoe crabs continue vanishing from our shores on our watch.

The Center’s Laiken Jordahl joined NPR’s Studio 1A today to discuss the looming threat of a border wall through Big Bend National Park, where DHS just issued the largest wall construction contract in American history.

A wall through Big Bend would turn this remote park into an industrial construction zone, sever wildlife from their only dependable source of drinking water, and lock the public out of one of the wildest rivers in the American West, effectively ending river recreation and whitewater boating on the Rio Grande.

We’ve been on the front lines with local communities fighting this from the start. Last month we sued DHS to stop wall construction in the Big Bend region.

We won’t let up until Big Bend is permanently protected.

There's no question the fossil fuel industry leaves widespread destruction in its wake.

Oil and gas production — a leading driver of climate change — fuels the superstorms, megafires, and droughts that harm people, degrade habitat, and push wildlife toward extinction, from polar bears to monarch butterflies.

Big Oil should be responsible for the devastation it wreaks for profit.

But two new bills in Congress could give the industry full legal immunity, leaving the public to deal with the fallout and shoulder the costs.

Legislators can halt these bills in their tracks and remind the industry it's not above the law — but they need to hear from you.

Tell your members of Congress to reject any legislation that would let Big Oil freely harm wildlife, people, and the planet. 🌍➡️ https://bit.ly/3RMgFus

Watch as Florida panthers, alligators, bears, bobcats, deer and coyotes cruise through wildlife crossings beneath highways as unknowing humans commute above them at 70 mph.

Large urban and agricultural developments and their infrastructure can be major barriers to all kinds of wildlife. Without proper planning, they can lead to fragmented habitats that constrain wildlife movement.

These limitations hurt animals. Habitat fragmentation limits their movement, impairing some animals’ ability to find food, shelter and mates.

Thankfully there are solutions to improve habitat connectivity, like underpasses and overpasses shown in the video.

Preserving wildlife corridors and connecting habitats is beneficial to both humans and wildlife alike.

We've been working to improve wildlife connectivity across the country. Learn more about this important work. ➡️ biodiv.us/connectivity

Another week of environmental fights and legal battles here at the Center.

From the Trump administration approving continued use of atrazine and reviving cyanide “bombs” on public lands, to new border wall contracts tied to Big Bend, there’s a lot happening right now that deserves attention.

But there’s resistance too — including new lawsuits to protect marine wildlife, growing wolf recovery in California, and renewed pushes to defend grizzlies and endangered sea turtles.

These stories are shaping the future of wildlife and public lands in real time. Follow for weekly updates, and take action against M-44 cyanide bombs at the link in our bio.

05/22/2026

Really bad news: The Trump administration has just reversed the ban on dangerous M-44s on public lands.

Wildlife-killing M-44 devices — aka “cyanide bombs” — are spring-loaded metal cylinders lure foxes, coyotes, birds, and others with a sweet-smelling scent.

It just takes a little tug before a deadly dose of poison shoots out, sending the animal into a slow and agonizing death.

They're used to kill wildlife deemed "undesirable" by agribusiness, but M-44s are indiscriminate. In 2024 alone they killed at least 4,664 animals — including many accidental deaths. They've also killed family pets and injured kids.

In 2023, after a decade of advocacy by the Center and our allies, the U.S. Bureau of Land Management banned the use of these devices on the lands it manages. But now, under the Trump administration, the agency has quietly reversed that ban.

We fought to get them banned before and we won. We'll do it again — but we need as many people to speak up as possible.

Tell the BLM to reinstate its ban on cyanide bombs right now. ➡️ biodiv.us/m44

Good news (heavy sarcasm): The Trump administration's U.S. Fish and Wildlife Service has finalized a review of the pesticide atrazine and has concluded that the potent, cancer-linked endocrine disrupter does NOT pose an extinction risk to any threatened or endangered animals or plants.

The court-ordered final review, which came in response to a legal challenge by the Center for Biological Diversity, was just released to the us last Friday.

The controversial finding contrasts sharply with a 2021 U.S. Environmental Protection Agency determination that the pesticide is likely to harm more than 1,000 protected species.

It's a common contaminant of water bodies, including drinking water, and so dangerous to both people and wildlife that it has been banned in more than 60 countries across the world. Yet, it is the second most widely used pesticide in the United States.

But don't worry, it definitely does NOT pose an extinction risk to protected species, according to the review! 😉

The Alaska Department of Fish and Game says killing bears will save the struggling Mulchatna caribou herd.

But scientists and conservation groups, including the Center for Biological Diversity, say the science behind this massive bear-killing program just doesn’t hold up.
The herd declined from around 200,000 caribou in the late 1990s to about 16,000 today. Independent experts say bears aren’t the reason.

Disease and lack of food, made worse by climate change, are driving the decline.

Despite that, Alaska authorized the killing of an unlimited number of brown bears across 40,000 square miles. Courts have already ruled against the program for lacking credible scientific support.
Killing bears won’t create long-term recovery for caribou. Wildlife management should be rooted in science, sustainability, and protecting entire ecosystems; not scapegoating and slaughtering bears.

The Center for Biological Diversity will always take an uncompromising stance to protect wildlife.

Please share this video to help make noise about what’s happening in Alaska. And if you want to support our fight for bears, caribou, and wild ecosystems, donate at the link in bio.
