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 future for all species, great and small, hovering on the brink of extinction.

We do so through science, law and creative media, with a focus on protecting the lands, waters and climate that species need to survive.

We want those who come after us to inherit a world where the wild is still alive. Join us

Our Commitment

The Center for Biological Diversity believes that social, economic and environmental issues are interconnected. It is necessary to promote and embrace diversity and justice to create the social change needed to protect the environment and all who depend on it.

We're fighting a growing number of national and worldwide threats to biodiversity, from the overarching global problems of unsustainable human population and climate change to intensifying domestic sources of species endangerment, such as off-road vehicle excess.

Based on our unparalleled record of legal successes — 83 percent of our lawsuits result in favorable outcomes — we've developed a unique negotiating position with both government agencies and private corporations, enabling us, at times, to secure broad protections for species and habitat without the threat of litigation.

We look forward to a future of continued expansion, creativity, and no-holds-barred action on behalf of the world's most critically endangered animals and plants.
