How does an environmental Libertarian think? What are his values? Is a Libertarian’s response to global warming to sweat it out and buy lots of sunscreen? Hardly. In fact, only free markets will save the grey wolf, the humpback whale, the snail darter and the spotted owl; without regulation, without ethanol subsidies, without the EPA, and without Al Gore! In this episode, Bob joins Dr. Mary Ruwart, a Libertarian who has studied environmental issues for most of her life, to learn why free markets are green markets.
