Center for Biological Diversity


Green sea turtle

The Center for Biological Diversity has been winning protection for endangered species and the wild places they need to survive for 25 years -- we've been called the "lean, mean endangered species machine" for our outstanding track record. We're the best investment you can make for a rich, biologically diverse planet in the future.

Help us continue our record-setting success in defense of wolves, polar bears, sea turtles and hundreds of other species. Please support our lifesaving work today with a gift online.
