Deforestation in the US

While deforestation has occurred throughout human history, the practice has increased dramatically in the past 50 years. According to the United Nations’ Food and Agriculture Organization, about 7.3 million hectares (18 million acres) of forest are lost every year, and roughly half of Earth’s tropical forests have already been cleared. In the continental United States, an estimate from the University of Michigan found that 90 percent of indigenous forests have been removed since 1600.
