Rainforests
Rainforest are the single greatest source of air on earth, but only cover 2 percent of the earths surface and is home to 2/3 of living species. Nearly half of the medical compounds used today are can be found in rainforests. Some studies show that rainforests are 70-100 million years old. Rainforests have 10 times the number of species per mile than that of North America. Some of the most widely known rainforests are the Amazon in South American, in Africa along the equator, and in the South Pacific like Indonesia and Philippines. Other rain forests are found in Central America, Mexico, Hawaii, and islands in the Pacific and Caribbean. Because of favorable weather all year round all life flourishes. Most rainforests wrap around the earth along the equator, with temperatures in the 80s and 160 to 200 inches of rainfall each year. Estimates of different life forms in the rainforest reach to 70 million.
Rainforest destruction is terrible. Today only half of the rain forest remains. In Brazil during the 1500s there were approximately 6-9 million indigenous people living in the rainforest, today there are only about 250,000. Conservative estimates show that up to 9000 species are going extinct each year. Today the world is experiencing the largest extinction since the dinosaurs.
