In the United States, where 15 percent of land is protected, conservation dollars are tied up on costly activities like lobbying, legal battles, and buying up some of the most expensive real estate there is. As the Nature Conservancy's lead scientist, M.A. Sanjayan, has observed, "Conservation has always cost less to do abroad than in the United States."
