Michael Crichton, a wonderful "fantasy" author, was an M.D. from Harvard. He was a very deep thinker and extremely well informed. These are his thoughts on environmentalism as religion and what the 'real' indigenous people are like in their societies. http://www.michaelcrichton.net/speech-environmentalismaseligion.html Our civilization came from what he describes. This piece raises many avenues of thought and discussion.
