Paul Sabin on Ehrlich, Simon and the Bet

Paul Sabin talks with host Russ Roberts about his book, The Bet. He uses an historic bet between Paul Ehrlich and Julian Simon over whether natural resources are getting scarcer as population grows to examine the evolution of the environmental movement and its status today. Sabin considers the successes and failures of the movement and the challenges of having nuanced public policy discussions on issues where both sides have passionate opinions.
