The World Without Us

We sat down with award-winning science journalist and author, Alan Weisman to talk about his best-selling book "The World Without Us." Find out what prompted him to write the book and where Weisman thinks the world is headed if we don't control our population explosion. Weisman is Laureate Associate Professor in Journalism and Latin American Studies at the University of Arizona. Learn more about his work here. The world population is now: over 6 billion.

In this segment, Ira talks with author Alan Weisman about what the world might be like if humans were suddenly to disappear from the planet. Would a human-free Earth be more environmentally friendly? Would a sudden removal of humans disrupt the planet's ecosystems still more? In his book "The World Without Us" (St. Martin's Press, 2007), Weisman says that in as little as two days without human intervention, the New York City subway system would be flooded -- and in as little as a year after a mass human disappearance, every nuclear power plant on Earth would have run out of coolant and failed or melted down. How long would it take the planet to heal itself after humans left? And what would happen to our cities, cultural artifacts, and other creations?

This is a holiday rebroadcast of a previously recorded Science Friday, so please don't try to call in.
