Overpopulation: An Interview With Alan Weisman, Author of Countdown
What is the right human population? The current seven billion? More? Less? Zero? Alan Weisman is the author of the best-selling The World Without Us, an examination of what would happen to the natural and built environments if people suddenly disappeared. Now, in his new book Countdown: Our Last, Best Hope For A Future On Earth?, he explains why population has grown so fast after growing slowly for thousands of years, then dares to consider the possibility that fewer humans might make for a better world, and covers recent developments in population control.
