One of the major environmental issues with the Himalayas is deforestation. Most of the trees in the Sub-Himalayas have been cut for land and lumber. Because of the deforestation‚ other issues like soil erosion and landslides have arisen. Overpopulation is another problem in the Himalayas. "Nearly 40 million people inhabit the Himalayas.

Tropical rainforests are currently a habitat that is currently experiencing serious losses. Some major reasons why the rainforest are having serious losses are because of agricultural expansion‚ urbanization‚ and the extraction of wood. Currently‚ the biggest cause is agricultural expansion which turned the forest into pastures and cropland to meet the growing needs for food. A study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from forests

Global warming is getting worse causing melting icecaps which is caused by rising temperatures and deforestation is happening which is also a cause of global warming. Deforestation is the damage of forests. Deforestation is mostly caused by humans because we cut down the trees to build building and other stuff. In the past the world was once
