Whether you're interested in the number of threatened plant species in various countries, changes in glacier mass, airborne lead levels, or the use of ozone-depleting compounds such as methyl bromide, check out the Global Data Portal from the U.N. Environment Programme. The site lets you download data on more than 450 economic and ecological variables or render them as a map, graph, or table. For example, there is a chart that depicts the change in forest cover for different countries between 1990 and 2000, with Brazil showing the biggest loss and China recording gains. The figures collected here provide the underpinnings for the U.N.'s Global Environment Outlook, an occassional report on the biosphere's condition, and other summaries.
