The environmental subweb is coming. A Letter to a Friend I am finally trying to briefly reply to your interesting and provocative letter. As you said, I also am not writing to persuade you in any sense, simply to lay out some of my beliefs regarding humans and the environment, and the environmental movement. I agree about the fallacy of blindly following ideological movements without a firm underpinning on logic and reality. Following an environmental movement with no personal knowledge of the subject is exactly the same.
Science is based on logic and examination of reality.
The definition of environmentalist is probably a pretty personal one, you decide whether you are or not and what that means. Other environmental groups and environmentalist individuals use the best reports of current science as the base for their beliefs and goals. Some branches of science have distinct environmental characteristics, such as ecology, botany, and zoology. Also the earth sciences like geology and atmospheric science, and the social sciences all have components which relate to the state of our environment and world condition. Many environmentalists draw on all these sciences for information which lead to their beliefs.
