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.

The measurement of biodiversity is complex and has a qualitative as well as a quantitative aspect. If a species is genetically unique — if, for instance, it's far out on a remote arm of the evolutionary tree, like the distinctive, peculiar platypus — its biodiversity value is greater than that of a species clustered with many similar species because it preserves a unique part of the ...

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.

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.

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 ...

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 destruction, invasive species and climate change, species are going extinct at up to 1,000 times the natural rate. The diversity of life that ...

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.

HOW WE DO IT • Compiling and analyzing data about species status and recovery. • Submitting legal petitions, filing lawsuits when necessary, using the leverage of our supporters' voices, and taking multiple other actions to ensure that imperiled species are federally protected.

Specifically President Biden must support a plan that … Declares the global extinction crisis to be a national emergency and commits $100 billion to saving the diversity of life on Earth.; Creates 175 parks, refuges and monuments to build toward protecting 30% of lands and waters by 2030 and half by 2050, a campaign known as 30x30.; Immediately provides $10 billion to …

Our information on plant species numbers is far from perfect. The International Union for the Conservation of Nature's Red List estimates that about 54 percent of evaluated plant species (not nearly all the plants on Earth) are threatened: 10,584 out of 19,738. Other estimates say about one in eight plants is considered at risk of extinction globally, putting the U.S. number at one-third.
