For the most part, extreme environmentalists are Godless. They often claim to be atheists or at least agnostics on the subject of religion. Many even ridicule religion, especially Christianity, calling it “superstition,” “backwards,” or “archaic.” They often blame for what they claim is the destruction of the world’s ecology on people who are religious and then use that as a basis to call hypocrisy on those same religious people. We’ve all seen it.
But, in general they also claim that their beliefs in humanism and nature are superior. However, they’d scoff at claims that they have merely replaced traditional religion with one of their own creation: environmentalism. They would argue that their beliefs are simply applied logic and does not represent that of religious zealotry.
