An article that Brian found, gives us the enviromentalists attitude in their own words. Some scary stuff... Here are a few of the quotes:

Human beings, as a species, have no more value than slugs. -- John Davis, editor of Earth First! Journal

I'm glad you have such a high opinion of yourself.

Phasing out the human race will solve every problem on earth, social and environmental. -- Dave Forman, Founder of Earth First!

Okayyyy... Whatever you say...

Cannibalism is a "radical but realistic solution to the problem of overpopulation." -- Lyall Watson, The Financial Times, 15 July 1995

Now that's just SICK!
