The Center for Biological Diversity works through science, law and creative media to secure a future for all species, great or small, hovering on the brink of extinction.

Protecting endangered animals and plants is the Center's core mission. From miniscule, nearly invisible fairy shrimp to gray whales and towering redwoods, all species have an intrinsic right to thrive. ABOUT OUR ENDANGERED SPECIES WORK The planet's wondrous web of life — which took 4 billion years to evolve — is vanishing in the blink of an eye. Under relentless pressure from habitat ...

At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature — to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a ...

Please join the Center for Biological Diversity's efforts to protect wildlife and wild places.

Action for endangered species underpins all the Center's programs. Our work has secured protections for more than 720 species and more than half a billion acres of wildlife habitat.

THE ELEMENTS OF BIODIVERSITY WHAT AND WHERE IT IS Biodiversity, n.

Biological diversity, often shortened to biodiversity, is the variation of life at all levels of biological organization, referring not only to the sum total of life forms across an area ...

BIODIVERSITY The Earth’s biodiversity — the variation of life at all levels — is the result of 4 billion years of evolution. And now it’s vanishing in the blink of an eye. Under relentless pressure from exploding human populations, animal and plant species are going extinct at 100 to 1,000 times the natural rate. The diversity of life that sustains both ecological systems and human ...

HALTING THE EXTINCTION CRISIS Our planet now faces a global extinction crisis never witnessed by humankind. Scientists predict that more than 1 million species are on track for extinction in the coming decades. But there’s still time to halt this crisis — and we need your help. Check out all the Center’s current online action alerts …

Under relentless pressure from habitat destruction, invasive species and climate change, species are going extinct at up to 1,000 times the natural rate. The diversity of life that sustains ecological systems and human cultures around the world is collapsing. In response, the Center's programs to save unique species and lands now reach beyond U.S. …
