Paul R. Ehrlich, American biologist and author

Paul Ralph Ehrlich is an American biologist, author and environmentalist known for his predictions and warnings about the consequences of population growth, including famine and resource depletion. Ehrlich is the Bing Professor Emeritus of Population Studies of the Department of Biology of Stanford University. Ehrlich became well known for the controversial 1968 book The Population Bomb, which he co-authored with his wife Anne H. Ehrlich, in which they famously stated that "[i]n the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now." This position has led historians and critics to describe Ehrlich as a neo-Malthusian.
