Please explain how deforestation, global warming and pollution are not shit that happens. They all happen with or without us to make them happen, deforestation, and pollution are usually the results of a volcanic explosion, but can also be the results of an asteroid strike. Global warming has happened many times before men had any hand in it. If it hadn't we wouldn't be here. We may contribute to any of the disasters you name as "made to happen" but we also are a force of nature, in other words we are shit that keeps happening. Don't forget that a beaver builds a dam for a beavers purposes, we build dams for our purposes which one is not natural?
