"Countdown: Our Last, Best Hope for a Future on Earth?" By Alan Weisman
Alan Weisman is the author of the critically acclaimed New York Times best seller The World Without Us.

And, how might we actually arrive at a stable, optimum population, and design an economy to allow genuine prosperity without endless growth?
