> If you ever manage to have a rational discussion with an environmentalist (extremely hard because they almost always turn to name-calling, change the subject, or other childish behaviors), you will discover that the root of their reasoning revolves around a belief rather than logic.

If you ever have a rational discussion with a human (or, for that matter, anything else that has a belief about what should be done), you'll find that -- its not limited to environmentalists. You can't get to a conclusion about what should be done without starting from an a priori belief about the criteria for what should be done, no matter how much logic gets used between the root belief and the conclusion.
