I think it's great that we have organisations like Greenpeace. In a pluralistic society we want to have people who point out all the problems that the Earth could encounter. But we need to understand that they are not presenting a full and rounded view.
I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.
I am involved in Greenpeace. And I just recently completely switched my diet over to near-veganism. So you try to do little things that you can. I recycle every single day. Every single thing in my house that can be recycled is.
