Do you see yourself as a worthless cockroach contributing to the collapse of human civilization? Probably not, but Stanford biologist Paul Ehrlich thinks precisely that about you.

Fifty years ago, he published arguably the worst book ever written, The Population Bomb, which declared that human overpopulation would cause mass starvation. Instead, the Green Revolution (led in part by ACSH co-founder Norman Borlaug) caused global food production to explode, and the world population more than doubled from 3.5 billion in 1968 to 7.6 billion today.
