With the historical perspective of The Song of the Dodo and the urgency of Al Gore’s An Inconvenient Truth, The Unnatural World chronicles a disparate band of unlikely heroes: an effervescent mad scientist who would fertilize the seas; a pigeon obsessive bent on bringing back the extinct; a low-level government functionary in China doing his best to clean up his city, and more. These scientists, billionaires, and ordinary people are all working toward saving the best home humanity is ever likely to have. What is the threat? It is us. In a time when a species dies out every ten minutes, when summers are getting hotter, winters colder, and oceans higher, some people still deny mankind’s effect on the Earth. But all of our impacts on the planet have ushered in what qualifies as a new geologic epoch, thanks to global warming, mass extinction, and such technologies as nuclear weapons and plastics.
