Term Papers on The Rain Forest
The Rain Forest The destruction of the rainforest is a problem that the people of the world can not continue to ignore. 14 percent of the Earth's land used to be covered by rainforests yet this number has dropped significantly to only about 6 percent (http://www.ran.org/ran/info_center/index.html). Rainforests provide the people of the world with many necessities, some of which would no longer be available if rainforests did not exist. In the last 50 years, rainforests have declined at a terrifying speed of 150 acres per minute or 75 million acres per year (http://www.ran.org/ran/info_center/index.html). People must open their eyes to the horrible tragedy that will inevitably occur if the citizens of the world do not realize the seriousness of this problem. To better understand the importance of the rainforest, one must be knowledgeable about what a rainforest actually is. The two main types of rainforests are temperate and tropical. Tropical rainforests are located in Latin and South America, Africa, Southeast Asia, and other areas in which temperatures stay above 80 degrees Fahrenheit year round. They can be found in 85 countries all over the world, however, 90 percent of them are concentrated into fifteen countries, each containing over ten million hectares. Tropical rainforests receive 160 to 400 inches of rain each year. Although these dense, damp forests cover just 5 percent of the Earth's surface, they can provide homes for between 50 and 90 percent of the Earth's plants and animals (http://www.davesite.com/rainforests/review1.shtml). Tropical rainforests consist of three distinct layers referred to as the forest floor, the understory, and the canopy. The forest floor contains very poor soil which is mainly due to the trees not allowing for ample sunlight to reach the ground. Because only one to two percent of the light at the top of the forest's canopy manages to reach the floor below, photosynthesis ceases to exist. On top of the soil lies a thin layer of the remains of millions of dead trees, plants, and animals which are quickly broken down by the numerous number of organisms on the floor (Nichol 45). It contains a variety of insects as well as larger mammals such as gorillas and jaguars. The understory is home to smaller mammals such as anteaters, lemurs, and tree kangaroos. It also contains small trees and numerous shrubs. The top layer, the canopy, is made up of the tops of trees which can grow to be over 200 feet in height. Here, trees receive the necessary sunlight to undergo photosynthesis which is crucial for the survival of the forest as a whole. Many tropical birds, monkeys, apes, snakes, and other animals reside in the canopy (http://www.davesite.com/rainforests/review1.shtml). Temperate rainforests are located along the Pacific coast of Canada, the United States, New Zealand, Tasmania, Chile, Ireland, as well as Scotland and Norway. Most temperate rainforests are much younger than tropical rainforests only being less than 10, 000 years old. The temperate rainforests differ from the tropical in that their soil is full of much more nutrients. Temperate rainforests are also much more scarce than tropical rainforests (http://www.davesite.com/rainforests/review1.shtml). The rainforests of the world are homes to just about every group of animals known to man and it would be impossible to give recognition to them all. The only animals that appear to be few in number are large mammals. The largest animal of the rainforest is thought to be the okapi, "a shy, elusive beast from west Africa (Nichol 56)." Gorillas, apes, the orang-utan of the Far East, gibbons, and chimps which can grow to the size of a human are also among the larger animals in the forest. A wide variety of monkeys including the tiniest monkeys in the world, the pigmy marmoset, live among the trees in the South American rainforests (Nichol 61). One of the rarest primates in the world, the golden lion tamarin, lives in a very small portion of the rainforest ... This is ONLY a preview of the article.
