The population is booming and Mike Hanauer of Zero Population Growth considers that the world's leading environmental problem. Population growth is already straining the world's environmental and energy resources. If current trends continue, the population of the U.S. could reach a half-billion in the next century and world population could triple to 14 billion. Hanauer speaks of what needs to be done to stem the population explosion.
