The U.N. Food and Agricultural Organization (FAO) and World Resources Institute (WRI) surveys indicate that the global rate of forest vcover loss between 1990 and 2005 was between 0.2% and 0.5% per year, and that at least another 0.1%-0.3% of the world’s forests were degraded every year, mostly to grow crops and graze cattle. If these estimates are correct, the world’s forests are being cleared or degraded exponentially at a rate of 0.3%-0.8% per year, with much higher rates in some areas.
