China has added over 170 million acres of forest since 1990, an area roughly the size of Texas, according to a new U.N. report. This is part of a larger trend where forests are regrowing in richer countries, including the U.S., Canada, Russia, and much of Europe. The report also notes that the world has lost around 20 million acres of forest per year for the past several years, mainly due to deforestation for farming and ranching. China's reforestation efforts have been driven by aggressive tree-planting programs, including a 2,000-mile-long belt of trees around the Taklamakan Desert.
