This year marks the 40th anniversary of the publication of Paul Ehrlich's The Population Bomb, one of the most influential and controversial books of the 21st century. The book was so powerful that leading conservative intellectuals mounted a campaign against it, branding it (along with Darwin's The Origin of Species) as one of the most "harmful" of the past two centuries. Now, Paul Ehrlich and his wife Anne are back with a new book, The Dominant Animal, which picks up on many of the central issues of The Population Bomb and reveals startling new research and analysis on the fate of our planet and humanity. Paul R. Ehrlich is Bing Professor of Population Studies and Professor of Biological Sciences at Stanford University. He is the author of hundreds of scientific papers, and numerous books including The Population Bomb and Betrayal of Science and Reason (Island Press, 1997). His latest book is The Dominant Animal: Human Evolution and the Environment, which he co-authored with his wife Anne.
