The Amazon Rainforest is one of the most important ecosystems in the world. However, it is slowly being destroyed. Areas of the rainforest are being cleared for farms and roads, and much of the wood is also being harvested and sold. There are several compelling reasons to protect this area. First, a significant number of pharmaceuticals are made from plants that have been discovered in the rainforest, and it's quite possible there are still important plants that have not yet been discovered. Secondly, the rainforest provides a significant portion of the world's oxygen and also absorbs great amounts of carbon dioxide. Without rainforests, global warming could accelerate.
