Mission: 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.

Results: According to the LA Weekly, we're "pound for pound, dollar for dollar, the most effective conservation organization in the country. "
