How to Feed the World
Hunger has wracked humanity since time immemorial. Nearly every major society has been shaped by famine; one estimate suggests that China suffered drought or flood-induced starvation in at least one province almost every year from 108 BC to 1911. Yet the struggle against hunger is a battle that humanity could finally win.
More cereals were produced annually in the last quarter of the twentieth century than in any preceding period, and more grain will be harvested this year than at any time in history. Since 1992, the number of hungry people worldwide has plummeted by more than 200 million, even as the human population grew by nearly two billion.
