Greenpeace is in the states as well. You also have the Sierra Club, which is a pretty legit group. On the animal side you have PETA (People for the Ethical Treatment of Animals), they are a bit more . . . militant. And then there's the SPCA (Society for the Prevention of Cruelty to Animals), and the Humane Association. Those last two aren't really in the same league as greenpeace.

The EPA is an administrative agency, and not really a good one at that. It's kinda the opposite of Greenpeace.
