Can the free market be tapped to improve our environment? That is the contention of a fascinating new book called Greener Than Thou, which makes the case for a new brand of ecological stewardship known as “free-market environmentalism.” Comments co-author, Terry Anderson: “In Greener Than Thou, Laura Huggins and I sort out the difference between green rhetoric and real environmental progress. It is not enough to preach, sue, and lobby. The real test is to make environment quality an asset, especially one that is sustainable because it is profitable. With case studies from Alaskan halibut to Bolivian bees to Mexican jaguars, we demonstrate that effective environmentalism relies on property rights and markets rather than government regulation.”
