Collapse - Jared Diamond

It is difficult enough for a rational discussion on reducing GHGs to take place during an election campaign. The aggravating thing is that this is only a small part of the problem we are facing. As Dr. Diamond points out in Collapse, How Societies Choose to Fail Or Succeed, there are any number of factors that can lead to a systemic collapse of a society. In the past these disasters have tended to be localized. In our interconnected world of the 20th Century the failure of human society will be global.

Geological history illustrates how there have been massive extinction events in the past. An example would be the Permian-Triassic extinction where > 95% of marine species and >70% of terrestrial species disappeared.

There has been a lot of speculation that a meteorite in the Yucatan peninsula caused the Cretaceous extinction. The evidence indicates that this and other extinctions were not just related to a single problem facing the world. There were several ongoing strains on the ecosystems prior to the meteorite impact that lessened the dinosaurs ability to survive. The meteorite was not a silver bullet but rather the coup de grace.

How we can tackle this problem when we can't even discuss the Green Shift on its merits?Recommend this Post
