They also remind you of good stories about how it is that market mechanisms actually deliver sound environmental policy better than any existing alternatives. My colleague at this Institute for Humane Studies seminar, John Hasnas mentioned in his lectures the case of the Audubon Society allowing natural gas drilling in the Rainey Wildlife Refuge in Louisiana, a piece of property that they own and manage. A PERC op-ed that summarizes the case well indicates that a common law approach to property rights and potential environmental harms does a better job of delivering both environmental quality and economic value.
