If you believe something, you can have a morality that means something as well. You can feel recognized as an individual within the universe; it can give meaning to who you are.
I stress that I am not attacking Friends of the Earth, Greenpeace, and the environmental movement in general. They have done some good work overall. I am merely pointing out that they can, and are, used to promote the New World Order, mostly (though certainly not in every case), without their knowledge.
