Greenpeace is not as active as they used to be, they are more of a fund raising organization now. One thing is for sure they do know how to make the news. I also have a lot of respect for members there, but I think some of the problems are with the senior members who have grown a little too soft.
For a real movement that gets things done visit http://www.seashepherd.org they are simply amazing.
Hopefully things turn around for the polar bears.
