Wolves face severe threats nationwide. States like Idaho, Montana, and Wisconsin have authorized or seen the killing of a large percentage of their wolf populations, including over 200 wolves in Wisconsin in just 60 hours.

We must end these senseless killings. Join Jason Momoa, Leonardo DiCaprio, and thousands more in the #RelistWolves effort. Raise your voice by sharing this video and visiting RelistWolves.org or SaveOurWolves.org.

Los Angeles is the world's only megacity where mountain lions and humans coexist. This unique proximity underscores a critical conservation challenge.

A proposed city wildlife ordinance is vital. It addresses habitat destruction and fragmentation, protecting not only cougars but numerous other species facing similar threats.

Los Angeles is the world's sole megacity where mountain lions and humans coexist. This unique situation underscores the critical need for effective conservation strategies.

A proposed city wildlife ordinance is vital for protecting cougars and many other species. It addresses threats posed by habitat destruction and fragmentation, aiming to preserve biodiversity within the region.

A mama bear and her adorable cub enjoyed a warm day at a pool in a canyon near the U.S.-Mexico border. The little one appeared to be just learning to walk.

This cub will mature in a land of vast, rugged wilderness, yet one also marked by complex human politics.

Observe a lynx as it leaps over a beaver dam within Alaska's Kenai National Wildlife Refuge. These remarkable felines possess an impressive jumping ability, capable of clearing over 20 feet from a crouched stance.

Their long, powerful hind legs are a key evolutionary adaptation. This specialized anatomy allows them to effectively ambush prey, particularly when navigating and hunting in deep snow environments.

A remote camera captured a mama coati and her six kittens roaming a mountain range along the U.S.-Mexico border in Arizona.

These mountains, known as the Sky Islands Archipelago, are a world-class biodiversity hotspot, and clearly, a hotspot for cuteness too. #BorderViews

Los Angeles is one of only two megacities globally where big cats, specifically mountain lions, live within city limits; Mumbai is the other. These mountain lions inhabit the Santa Monica Mountains, just north of the city, including the Santa Monica Mountains National Recreation Area.

A new report highlights the critical importance of wildlife crossings. These crossings enable Southern California mountain lions to navigate fragmented landscapes safely and significantly reduce the risk of vehicle collisions. Learn more about this vital conservation effort.

A data visualization highlights trucking accidents, deaths, and injuries on a hazardous California route. This route is where ExxonMobil plans to truck offshore oil to market. Data is based on CHP records from 2015-2021.

After the Trump administration stripped federal protections from gray wolves, states now control their fate. While California and Colorado celebrate new wolf residents, Wisconsin, Idaho, and Montana are increasing wolf culling.

Our "Saving Life on Earth" webinar on July 8, 2021, featured our experts discussing ongoing efforts to regain wolf protections and how you can help. Learn more at saveourwolves.org.

Summer in the U.S. Southwest and northern Mexico brings intense heat, but also much-needed monsoon rains. This seasonal relief is vital for the arid region.

Recently, a borderlands remote camera captured numerous videos of a black bear thoroughly enjoying a cooling canyon pool, a welcome respite from the summer temperatures. #HotBearSummer

Emperor penguin colonies in Antarctica face severe threats. Climate change is causing sea ice to melt and break up prematurely, leading to rapid declines and the vanishing of these iconic birds.

Their survival depends on immediate action. Please urge the U.S. Fish and Wildlife Service to grant emperor penguins full protections under the Endangered Species Act.

Speak up for these beloved birds today: [https://biodiv.us/3gUhlsQ](https://biodiv.us/3gUhlsQ)

The Center for Biological Diversity is hosting a webinar with Terry Spahr, director of the documentary "8 Billion Angels." This film explores how global population growth strains our natural resources.

The event will feature a discussion and Q&A with Spahr, the Center's Sarah Baillie, and World Population Balance Executive Director Nandita Bajaj. They will examine how population pressure threatens our oceans, rivers, land, and air, and discuss solutions including women's empowerment and a transition from fossil fuels.

Wildland firefighters in southwestern China recently captured remarkable drone footage of a famous wild elephant herd. The video shows the elephants taking a collective nap in the forest.

This rare footage offers a unique opportunity to observe sleeping pachyderms. A highlight is a squirmy youngster who can't quite stay still.

Nevada stands on the frontlines of the extinction crisis, home to hundreds of unique, imperiled plants and animals found nowhere else on Earth. Species like the Mount Charleston blue butterfly, Dixie Valley toad, Devils Hole pupfish, and Tiehm’s buckwheat face severe threats.

A "Saving Life on Earth" webinar, featuring Nevada State Director Patrick Donnelly, explores how protecting these narrowly endemic species, utilizing the powerful Endangered Species Act, contributes to global conservation. Learn how the Center for Biological Diversity takes action against threats from ski-resort expansion, energy production, and pervasive groundwater overuse.

Discover how you can support the Center's vital work to save Nevada's rare flora, fauna, and their essential ecosystems.

The beaver, North America's largest rodent, is renowned for its engineering prowess. It acts as a master builder and hydroengineer, skillfully constructing dams and lodges that reshape landscapes.

Beyond these impressive capabilities, recent video evidence from Utah's Zion National Park suggests another surprising trait: the beaver is also a serious proponent of self-care.

Florida's diamondback terrapins are needlessly drowning in blue crab traps. A simple, effective solution exists: "bycatch reduction devices" (BRDs).

These devices, attached to trap openings, prevent most terrapins from entering, significantly reducing accidental drownings. We are urging Florida to mandate BRDs on all blue crab traps statewide.
