Paul Ehrlich, co-author with Anne Ehrlich of "The Dominant Animal: Human Evolution and the Environment"

Host Chris Andreae speaks with Paul Ehrlich, co-author with Anne Ehrlich of The Dominant Animal: Human Evolution and the Environment. 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. Ehrlich says The Population Bomb was too optimistic and that in many ways, the situation is far worse today than he could have imagined when he wrote the book in 1968.
