On this week's Power Hour Alex Epstein interviews ecologist Patrick Moore, cofounder of Greenpeace and author of "Fake Invisible Catastrophes and Threats of Doom." In his book Moore thoroughly debunks 11 alleged current or imminent catastrophes, from mass species extinction to ocean "acidification" to the near death of the Great Barrier Reef. In this interview Alex asks Moore about the false assumptions that drive our propensity to believe in "fake invisible catastrophes," including the assumption that human impact is inevitably destructive because it disrupts an alleged perfect, delicate balance of nature. More debunks this "delicate balance" idea thoroughly with numerous examples, above all with CO2 levels--which, he argues, were on a natural and deadly downward trajectory toward mass plant death until human beings restored some of it to the atmosphere.
