Rainforests are the Earth's oldest living ecosystems. They are so amazing and beautiful. These incredible places cover only 6 % of the Earth's surface but yet they contain more than 1/2 of the world's plant and animal species! Rainforests are the source of many items that we all use in our own homes. We eat several foods from the rainforest and many medicines are made from ingredients found only in these areas. Right now, we should conserve the Tropical RainForests by ecotourism and rehabilitation. Protect Endangered Trees. Save an Acre of Rainforest Today!
