The Center is an amazing group that really gets things done, both in court and out. They wrote the petition that got the polar bear listed under the Endangered Species Act, work to enforce laws to help fight global warming, and help protect public lands and all kinds of species from destructive activities. I don't know exactly how many species they've gotten federally protected, but it's a lot. I'm not what you'd call wealthy, but I give to CBD regularly because what they do is crucial.
