The land is hardly a good pasture and will never replenish itself. Loggers are cutting trees and spoiling streams. Dams are cutting off streams, flooding land, and disturbing the lives of natives.

In Peru the forests are being cleared for the production of coca for cocaine production. Tropical rainforests cover only seven percent of the earth. One of the large programs destroying the forest is Grande Caracas, which includes a giant mining complex, Polonoroiste, and a highway and settlement scheme. The process for iron-ore includes the need for charcoal, easily obtained by destroying the rain forest 1, 2/ "Playing With Fire".

At the currant rate the forests will be nothing but scrubby grasslands in 50 to 100 years."It's dangerous to say the forest will disappear by a particular year", says Philip Fearn side of Brazil's National Institute for Research in the Amazon, "but unless things change, the fores will disappear". 4/ The destruction of the rainforest would affect more than just South America.

It would affect the whole earth. "If the forests disappear, so will more than 1 million species-a significant part of earth's biological diversity and genetic heritage."Half of the earths biological diversity is harbored by the rainforests, according to some. 5/ "The rainforest houses around 80 percent of the worlds insects. Nine out of every ten primates (monkeys, gorillas, apes) live in rain forests.

In a typical 4 square mile patch of rain forest there is an estimated 750 species of trees, 125 types of mammals, 100 types of reptiles, and 60 of amphibians.

As trees are cut down and the forest's are burned the plants are destroyed, many of which are used in medicine. A quarter of all medicine contains plant material found only in rain forests.

Scientists feel there are a wealth of undiscovered chemicals and things to be learned from the forest. The forest creates a large cloud cover which would effect our temperature and climate. Because it generates such large amounts of cloud it has a great affect on global warmth. The trees are also a storehouse of carbon dioxide, which is released when burned. This will magnify the greenhouse effect. Others, such as the Indians and rubber tappers way of life is in danger.

6/ "Rainforest S.O.S". Nature Canada, summer, 1988, Pg. 1-4 There is a great challenge in trying to end the destruction of the rain forests.
