Since our founding in 1875, we have been the pathfinders for creating healthy forests from coast to coast.

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.

Cousteau understood before others did how critical our Water Planet is to our survival. And he dedicated his life to learning about what lay beneath the sea… creatures, plants, entire ecosystems, all of the hidden treasures whose life cycles impact our own. With global warming, increased shoreline development, pollution, plastic infiltrating our oceans, the mass extinction of species that have survived millennia, the mandate to protect what we love has never been as urgent as it is today. The only way to protect what we love is to understand the levers that keep it alive, resilient and sustainable. The Cousteau Society has been exploring the seas since 1975, establishing protected areas for endangered species, advocating for the silent world which cannot advocate for itself, and educating children and adults so that they can carry on his legacy of protecting our Water Planet.

The Xerces Society for Invertebrate Conservation is an international nonprofit organization that protects the natural world through the conservation of invertebrates and their habitats.
Our name (which is pronounced Zer-sees, or /ˈzɚˌsiz/) comes from the now-extinct Xerces blue butterfly (Glaucopsyche xerces), the first butterfly known to go extinct in North America as a result of human activities. The Xerces blue’s habitat was destroyed by development in the sand dunes of San Francisco, and the species was declared extinct by the 1940s.
