The Oceans: Our Last Frontier

The gold rush is on for the world's oceans and their resources. They promise not just oil, but precious minerals, potential biofuels, food sources, medical discoveries, and strategic advantages for the world's superpowers. Guest host Barbara Bogaev explores whether this new Blue Economy will stress the ocean's already fragile ecosystem beyond its breaking point.

Later on the program, a new book traces the flaws in our modern day criminal justice system to an unlikely source: Prohibition. A new look at the war on alcohol.
