Predicting the Limit of Our Population
How many people can the Earth sustain? According to author and journalist Alan Weisman, "the planet just seems to be bursting at its seams."
Today on Talk of Iowa, host Charity Nebbe interviews Weisman, who tackles that question in his new book, Countdown: Our Last, Best hope for a Future on Earth? She talks with him about what he learned by traveling the globe and studying different cultures and his vision of the future.
Alan Weisman will speak tonight, Monday February 24, at Iowa State University. The lecture begins at 8 p.m. in the Great Hall of the Memorial Union.
