M-44 "cyanide bombs," spring-loaded devices that lure and poison wildlife, are back. These indiscriminate devices cause agonizing deaths for foxes, coyotes, and birds, and have also killed pets and injured children. In 2024 alone, they killed over 4,600 animals.
In 2023, after a decade of advocacy, the U.S. Bureau of Land Management banned M-44s on its lands. However, the agency has now quietly reversed this ban under the Trump administration.
We successfully fought to ban them before and will do so again. Your help is crucial.
The Center’s Laiken Jordahl recently discussed the looming threat of a border wall through Big Bend National Park on NPR’s Studio 1A. The Department of Homeland Security (DHS) has issued the largest wall construction contract in American history for this region.
A wall would transform this remote park into an industrial zone, severing wildlife from vital water sources and blocking public access to the Rio Grande, effectively ending river recreation.
We've been on the front lines, suing DHS last month to stop construction in Big Bend. We are committed to its permanent protection. Please share this message to raise awareness and support our ongoing efforts.
Florida panthers, with likely fewer than 200 remaining, face critical habitat loss in southwest Florida. Development confines them to shrinking pockets, forcing dangerous crossings and threatening their survival.
Now, another large-scale residential and commercial project threatens to eliminate nearly 5,000 more acres. This will inevitably lead to increased roads, vehicle strikes, and deadly conflict over their limited space.
The Center for Biological Diversity and partners are challenging federal approvals in court to halt this destruction. Help support their vital fight to protect Florida panthers before it's too late.
Environmental and legal battles persist, with the Trump administration approving continued atrazine use and reviving cyanide "bombs" on public lands. New border wall contracts also threaten Big Bend, posing significant risks to wildlife and natural habitats.
Despite these challenges, resistance is strong. New lawsuits protect marine wildlife, wolf recovery grows in California, and efforts defend grizzlies and endangered sea turtles. These ongoing actions are shaping the future of conservation. Follow for weekly updates and take action against M-44 cyanide bombs via our bio link.
Federal logging plans threaten ancient trees in Alaska’s Tongass rainforest. The U.S. Forest Service proposes clear-cutting nearly 1,655 acres of old-growth habitat, vital for species like Alexander Archipelago wolves, Pacific salmon, and Queen Charlotte goshawks.
These centuries-old forests also act as a crucial natural buffer against climate change, storing vast amounts of carbon. Destroying them would release this carbon and eliminate a key environmental defense. Urge the Forest Service to abandon this destructive proposal and protect these irreplaceable trees.
An Alaska Superior Court ruling permits the state to kill an unlimited number of black and brown bears across 40,000 square miles of southwest Alaska this summer. The state claims this "bear control program" will boost a struggling caribou herd, but there is no scientific evidence to support this assertion.
Cooper Freeman, Alaska director at the Center for Biological Diversity, expressed concern about the "unlawful plan's irreversible consequences" and the lack of scientific basis. He emphasized the need to protect wildlife based on science, not "disgraceful waste of the state’s limited resources."
The Center for Biological Diversity and Alaska Wildlife Alliance are collaborating to stop this program. Support their efforts in this critical fight.
The Alaska Department of Fish and Game plans to kill bears to save the struggling Mulchatna caribou herd, which has plummeted from 200,000 to 16,000. However, scientists and conservation groups, including the Center for Biological Diversity, contend this program lacks scientific support. Courts have already ruled against the initiative.
Independent experts identify disease and food scarcity, exacerbated by climate change, as the primary drivers of the caribou's decline, not bear predation. They assert that killing bears will not achieve long-term recovery. Wildlife management should prioritize science, sustainability, and ecosystem protection over scapegoating.
For us, every day is Endangered Species Day. The extinction crisis threatens countless species, from whales to wildflowers. For 37 years, the Center for Biological Diversity has fought on the front lines, securing protections for hundreds of imperiled species and over 700 million acres of habitat. We believe every living thing matters.
Our work has never been more urgent. Hope lies in collective action; when people unite for the wild, we win. We are committed to ensuring endangered species not only survive but thrive, protected for generations to come.
Every species deserves a future. While today is Endangered Species Day, the fight to save wildlife is a daily commitment. The extinction crisis threatens countless species, from sea turtles to ancient forests, across our planet.
For nearly four decades, the Center for Biological Diversity has tirelessly protected the wild places animals call home, and we remain steadfast in our mission.
Join us in defending the wild before it's too late. Today, your impact is doubled as all donations are matched.
New video from a remote camera in southern Arizona's Sky Islands captured a rare jaguar, "Cinco," moving through the area in March and April, alongside bears and mountain lions. First filmed in 2025, this sighting underscores the jaguar's rightful place, despite threats like border wall construction, mining, and drought. Jaguars, the world's third-largest cats, once ranged extensively across the U.S. Southwest.

Alaska has confirmed a plan to kill an unlimited number of bears across 40,000 square miles, including near national park borders. Game agents will shoot bears from helicopters. This controversial initiative aims to boost a struggling caribou herd, despite a lack of scientific evidence that bear culling will be effective or address the caribou's underlying issues.
The Center for Biological Diversity has sued to stop this cruel and illegal plan. Your support is vital to help protect Alaska’s bears.
Florida panthers, with likely fewer than 200 remaining, are confined to shrinking habitats in southwest Florida. Development isolates them, forcing dangerous crossings and increasing threats to their survival.
A new large-scale project now threatens nearly 5,000 more acres, promising more roads, vehicle strikes, and deadly conflicts over diminishing space.
The Center for Biological Diversity and partners are challenging federal approvals in court to stop this destruction. Please support our fight to protect these panthers before it's too late.
The Endangered Species Act (ESA) secured a major victory last week as growing opposition halted the House of Representatives' effort to roll back this vital wildlife protection law. As Executive Director Kierán Suckling notes, the ESA is one of the world's most effective conservation laws, having prevented 99% of protected species, including bald eagles and gray wolves, from extinction.
This triumph benefits countless species like whales, sea turtles, and monarch butterflies, underscoring the power of collective voices. We extend our deepest gratitude to all Center supporters whose advocacy made this win for the wild possible.
California's iconic redwoods are at risk from a Highway 101 expansion. This project threatens to cut into the essential root systems of ancient trees on the North Coast, leading to their weakening, decline, and death. With less than 5% of original redwood forests remaining, these vital ecosystems cannot recover once damaged.
Governor Gavin Newsom has the authority to stop this plan. Urge him to protect these irreplaceable redwoods before it's too late. Act Now.

The Trump administration is threatening Big Bend National Park, a national heritage site, by planning to wall off river access points. This 517-mile sector, a vital part of the U.S.-Mexico border, faces imminent construction.
Such a wall would cut off wildlife from the Rio Grande, their sole water source, destroy cultural sites, and lock the river behind steel. This move reflects a disturbing disregard for public lands, seen as political vandalism rather than security.
Join the fight to protect Big Bend. Learn more at www.biologicaldiversity.org/campaigns/border_wall/. Contact your Congressional representatives at 202-224-3121 and urge them to strip federal funding for border wall construction in the region.
The Trump administration is pushing to construct a border wall through Big Bend National Park, a crown jewel of America's national heritage. These plans would wall off critical river access points, isolating wildlife from their only water source, the Rio Grande. Such construction would also destroy cultural sites and lock the river behind a steel barrier, an act of political vandalism, not security.
We have been fighting border wall construction for years. Learn more about our work: www.biologicaldiversity.org/campaigns/border_wall/.
