Question for the Americans out there

So, over here we have organisations, like Greenpeace (Greenies), who are all about protecting the animals and old growth forest etc. and they go out and protest and run little boats in the way of whaling ships and tie themselves to trees that are about to be logged etc.

What would be the equivalent group in America? Anyone?
