“Many of the world’s forests appear to be making a comeback, and some are more thickly forested now than they were nearly 200 years ago.” this, according to the Environmental News Network, which reported on a National Academy of Sciences study which showed that the United States and China had the greatest gains in forests over the last 15 years. Indeed, researchers found that despite concerns about deforestation, timber-size trees increased over the past 15 years in 22 of the 50 countries with the most forests. Experts attribute this to increasing prosperity, since almost every country with per capita income of roughly $5,000 or more has turned from deforesting to reforesting their land.
