题型描述: 段落翻译
Deforestation Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees. Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Trees play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests mean larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming.
