The world’s forests are continuing to shrink, but at a slower rate than five years ago, the U.N. Food and Agriculture Organization said yesterday. Since 1995, the world has lost 22 million acres of forest per year, a figure 20 percent lower than the previous five years. Forests are disappearing most rapidly in Africa and Latin America, while (oh-so-natural) tree plantations are being planted quicker than trees are being cut down in the U.S. and Europe, causing forest acreage to increase in those regions.
