Deforestation In North America

Although most of the areas cleared for crops and grazing represent permanent and continuing deforestation, deforestation can be transient. About half of eastern North America lay deforested in the 1870s, almost all of it having been deforested at least once since European colonization in the early 1600s. Since the 1870s, the region's forest cover has increased, though most of the trees are relatively young. Few places exist in eastern North America that retain stands of uncut old-growth forests. In addition, while some forests are being cleared, some are being planted. The United Nations Food and Agriculture Organization (FAO) estimates that there isare approximately 1.3 million square km (500,000 square miles) of such plantations on Earth.
