The Medea Hypothesis suggests that the success of a species on Planet Earth leads to predictable disaster. For example, plant life expanded to the point that it produced the Ice Age. Plants lack intelligence so there was nothing that they could do about it. The success of the human species is causing irreversible damage to our ecosystem. This raises the fundamental question about whether we are smarter than plants. Recent scientific evidence from biology has introduced a new problem in addition to the evidence that the human species is responsible for global warming. Plant plankton produce 50% of the earth's oxygen. One degree of ocean warming has destroyed 40% of the plant plankton. The question is no longer whether we face disaster according to the linked article. The issue is whether we face disaster or catastrophe.
Unfortunately, the Copenhagen Conference was a failure. The coming Cancun Conference gives us another shot at developing a response to the scientific evidence that is overwhelmingly validated by the scientific community. Apparently, we are intelligent enough to understand the problem of human contribution to ecological disaster or catastrophe. The real question is whether we will listen to the scientific community or to experts like Karl Rove and Rush Limbaugh who claim that the purported threat of ecological disaster is "so 70's"
