Suppose you need to know what percentage of land in Uganda is set aside in reserves, or how many of Australia's 260 mammal species are threatened, or how many wild orchids are legally sold each year. Track down these nuggets (the answers are 7.9, 58, and 343,801) at EarthTrends, a new environmental almanac packed with facts and figures of value to policy-makers, researchers, and even teachers hoping to jazz up a lecture. Compiled by the World Resources Institute in Washington, D.C., the data cover more than 140 countries as well as regional and global trends, with topics running from energy production to fish consumption to forest loss. For each of 10 major themes (agriculture and food, climate and atmosphere, and so on), you can call up tables, country profiles, and downloadable maps.
