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