Biologist, Norman Myers, states "rainforests are the finest celebration of nature ever known to the planet" (1). There are three main types of rainforests; temperate, sub-tropical, and tropical. Most of the rain forests still left in the world today are tropical. Tropical rain forests cover less then 6% of the earth, yet they contain half of the world’s species. As a matter of fact, rain forests support 90,000 of the 250,000 identifies plant species.
This equates to nearly 150-200 inches of rain per year. Over half of the world’s population of plants and animals can be found in tropical rainforests (Schomp 5-9). In only one tree, about 200 different species are living. To be named a “tropical rainforest”, it must contain a large diversity of species, experience direct sunlight, receive lots of rain, and obtain high humidity levels (Biomes Ch. 5).
This rainforest has a great variety of plants and animals. 1/5 of the world’s plants and 1/10 of all mammal species are found there. Africa: Central Africa has the world’s second largest rainforest. In the southeast, in the large island of Madagascar, the land was once intensively forested, but sorrowfully much of it has vanished. The island of Madagascar is home to many unique plants and animals not found anywhere

Average annual rainfall is between eighty and one hundred inches, while some forests receive four hundred inches of rain a year. "Occupying no more than seven percent of all the space on earth, they harbor at least half-possibly seventy-five percent -of all forms of life" (Stone 75). This makes it apparent that the importance of rain forests directly effects the world's ever-expanding human population and how we are linked to the massive pressures on tropical rain forests.

The Amazon Rainforest is located south from the Equator. It passes through nine different countries, but 60% is located on Brazil. The Amazon River is 4000 miles long; this is about the same distance that separates New York from Berlin. The size of the Amazon Rainforest is 2.3 million square miles this is equivalent area to 2/3 of the U.S. The largest reservoir of fresh water is on the Amazon.
Specifically, Central America, South America, Southern Asia, and Australia (which however, goes through a dry spell twice a year). The Amazon Rainforest is the largest tropical rainforest in the world; located in northern South America. It is three million square miles. Which is nearly the size of the United States. Tropical Rainforest have warm temperatures year around, and high rain fall.

Deforestation has to do with the permanent destruction of forest and wooded lands that are natural to that specific area. This means that deforestation includes the destruction of forests and wooded land where there is a canopy. Deforestation does not have anything to do with the removal of trees from plantations or industrial forests (Bragaw 1999). Deforestation is a major topic in our present day life. Little is known about the tropical forest and they are disappearing at an alarming rate.
The Causes of Deforestation in the Amazon Rain Forest The Amazon Rain Forest crosses several national boundaries in South America, although the majority of it is located in Brazil. It covers over 3,562,000 acres, making it the largest in the world. But globally, over 138,600 acres of rain forest are lost each year to deforestation, 50,000 of those in Brazil alone (Holdsforth), and the world's rain forests are quickly disappearing. Deforestation in the Amazon occurs primarily for three reasons: clear-cutting, fragmentation, and edge effects. The term "deforestation" refers to the clear-cutting of large sections of primary or original-growth forest, which causes the loss of native species of plant and animal life.
