Author's Note: How Zero Population Growth Works

Nearly 50 years later, it's easy to look back at Paul Ehrlich's dire predictions about population growth and scoff. Yes, England and India still exist, and the world has managed to feed itself – just barely in some places – while doubling in population since 1968. But Ehrlich's call to action, as overstated as it was, had its desired effect. The issue of population growth entered the national and international conversation. Today, the United Nations has a dedicated Population Division that monitors population trends as they relate to sustainable development worldwide. Ehrlich's original Zero Population Growth organization has spawned other global nonprofits dedicated to eradicating poverty, protecting the environment and promoting greater reproductive rights for women.
