China has led the world in new tree planting; in fact, over the last several years, China has planted 40 percent as many tress as the rest of the world put together. Since 1981, all citizens of China older than age eleven (and younger than sixty) have been formally required to plant at least three trees per year. To date, China has planted approximately 100 million acres of new tress. Following China, the countries with the largest net gains in tress include the U.S., India, Vietnam, and Spain.
