Roger Thurow and Scott Killman are the co-authors of Enough: Why the World’s Poorest Starve in an Age of Plenty, a new book published by Public Affairs, in which they argue that mankind has the knowledge and resources to end world hunger, and that this goal might actually be accomplished in this generation.

In the video below, Thurow explains how the Green Revolution helped end hunger in most of the world, but stopped short of Africa.
