I received The World Without Us
The premise is what would happen if humanity were removed from the planet, but everything else, including all other creatures, remained in place. How long would our presence even be recognizable? In some instances it would not be long. Indeed, this book should put an end to those doomsday scenario movies with people living in the New York City subways. Without their hundreds of massive electric pumps, the subway tunnels would flood with the first good rain.
A good read, one of five nominees for the National Book Award for nonfiction for 2007.
