Habitats and Threats


Heading Toward 10 Billion People
The planet hosts more than 7 billion humans, with 227,000 added daily. Our expanded Population and Sustainability Program — the only one of its kind — tackles what it means for us and the wildlife we love.

Hear the Call of the Wild? 
You're not alone. Our endangered species ringtones have been downloaded almost 600,000 times in 177 countries.

Center Videos — Watch Now
Get to know our many facets by checking out some of our favorite Center videos, from a description of our group's goals to polar bear shorts and a hilarious dung beetle biopic.

Deadly Waters
Sea-level rise driven by climate change threatens 233 protected species, according to a Center report — learn more about the issue and what needs to happen.

Amphibians and Reptiles At Risk
These amazing cold-blooded creatures possess clever adaptations that have let them brave millennia — but they now face threats more chilling than ever before.

Don't Frack With Our Planet
Fracking’s bad news: Sullied water. Greenhouse gas pollution. Threatened wildlife. Learn more about the Center's fight to halt fracking in California and beyond.

Oceans Plastics Pollution
Plastic never goes away. And it’s increasingly finding its way onto our beaches and into marine habitat for fish, whales, seals, birds and more. Find out what we're doing about it.

Creative Media
We don't only use litigation, science and organizing to save species. See how the Center gets creative, from offering free e-cards to iPhone apps.

Save Our Bats
White-nose syndrome has killed almost 7 million bats in the United States. Help us fight this startling crisis that's threatening whole populations of these creatures of the night.

Endangered Oceans
The world’s oceans are in trouble. Learn about ocean acidification, what the Center is doing to fight it — and what you can do to save sea life, from corals to clownfish.

Restoring the Gray Wolf
Some of the country's most critical predators are under attack. Learn how we're defending them across the nation.

ESCEndangered Species Condoms Project
We've distributed hundreds of thousands of free Endangered Species Condoms to show how unsustainable human population growth and is driving species extinct. Get yours.

condorSaving Tejon Ranch
Megadevelopments threaten to obliterate some of the California condor's most vital habitat. Learn about the strong stance we're taking to save all of Tejon Ranch.

Polar bearAn Arctic Icon Changes the World
Meet the beloved bear that made millions — even the recalcitrant Bush administration — sit up and take notice of warming's effects.

San Pedro RiverSaving the San Pedro River
The Center takes on Army brass and developers to save a transnational treasure trove of biodiversity.

Carnivores at Risk
Predators like jaguars, wolves, and bears can be prey, too — learn about the threats they face and their critical role in ecosystems.

Off-road to Ruin
Off-road vehicles tear up habitat, directly harm species, and pollute the air. We work hard to keep their destruction in check.
