The Causes and Effects of Deforestation in Tropical Rainforests Tropical rainforests are the most alive places on earth. Covering less than 12% of the land's surface, the rainforests are home to more than half of all living species (Lewis, 4). 90% of all non-primates reside in tropical rainforests. Two-thirds of known plants, 40% birds of prey, and 80% of all insects are found only in tropical rainforests. Of the 2.5 to 5 million animals species thought to exist, only about one-half have been identified to date. The vast majority of rainforests are found in Brazil (Amazon), South Asia, Africa, and Central America. (WRM, 16). The two main types of rainforest are equatorial rainforests and tropical rainforests. Equatorial rainforests make up about two-thirds of all rainforests, and is found bordering the equator in Brazil, Zaire, and Southeast Asia. The temperature and the rainfall in equatorial rainforests are the same year-round. Tropical rainforests, on the other hand, are found north and south of the equatorial rainforests, and they have definite wet and dry seasons. (http://www.waste.org/…). Rainforests are named so because of the rain they create within themselves. From morning to noon, as the sun heats the forests, the trees transpire hundreds of liters of water. This water forms large cumulonimbus clouds which start raining by 2 or 3 o'clock in the afternoon. Most of the rainfall stays on leaves of the tallest trees, in the canopy. The next day, this water evaporates to fall again as rain. (http://www.waste.org/…). Tropical rainforest vegetation grows in layers.
