Jonah, unsurprisingly the U.N. is actually part of the problem. As I detail in The Really Inconvenient Truths (a great Christmas gift!), the U.N. Environment Program’s Convention on International Trade in Endangered Species actually encourages poaching. It’s an international version of the perverse incentive that is the Endangered Species Act. If there’s a demand in China for Indian tiger, erm, parts, then, as Barun Mitra has suggested, the answer is tiger farms. But under CITES, that’s a no-no. And so we have tigers approaching extinction because of enviro anti-market fundamentalism. To paraphrase someone else, if the U.N. is the answer, you’re asking the wrong question.
