        Rain forest cover less than six percent of the Earth's total land surface, but they are the home for up to three-fourths of all known species of plants and animals; they also contain more species as yet undiscovered. Recent studies suggest that this great diversity of species is related to the apparently dynamic and unstable nature of rain forests over geologic time. Despite their appearance of fertile abundance, rain forests are fragile ecosystems. Their soils can quickly lose the ability to support most forms of vegetation once the forest cover is removed, and some soils even turn into hard LATERITE clay. The effect of forest removal on local climates is also often profound, altrough the role of rain forests in world climatic changes is not yet clear.
        Despite the enormity of the Amazon Basin, the natural balance of aquatic systems in the area is increasingly more threatened. Deforestation by colonists and corporations has contributed to serious erosion problems in the region. Increased use of pesticides has threatened more and more animals dependant on the aquatic environment in recent years. Increasing humam population pressure has led to overfishing an depletion of once abundant fish an mammal species.
        The Brazilian pirarucu is an example of a native fish species that is currently approaching extinction due to the above-mentioned factors. This species is among the world's largest freshwater fish, and is found many in many eastern Amazonian waterways. Because it is an air-breather, and must surface frequently, it bas become easy prey for Brazilian cabocloFisherman.

        The Manatee is another species that has been hunted ruthlessly by locals and commercial fisherman. It has become one of the most threatened species in the 4.7 million square mile Amazon Basin. The Amazon manatee, the smallest of the world's manatees, is about 10 feet long and weights more than 1000 pounds. It has been hunted since the 1700s. Its hide and blubber are used for industrial purposes, while its meat is considered a delicacy. Though these mammals have been officially protected since 1967. However, this hasn't stopped local people from ruthlessly hunting them.

        For centuries, people made little impact on the Amazon and its drainage basin. In recent decades, however, the combined activities of loggers, farmers, ranchers, miners, and road builders have destroyed more than 518,000 sq km of forestland, and the rate of forest depletion has been estimated at 26,000 sq km annually. Never-the-less, much of the region remains a wildness.

        Throughout history, humans have encroached on rain forests for living space, timber, and agricultural purposes. In vast portions of upland tropical forests, the practice of "shifting cultivation" has caused deterioation of the primary forest. In this system of agriculture, trees are killed in small plots that are cropped for two of three seasons and then abandoned; if the plots are recultivated before primary vegetation has reestablished itself, a progressive deterioration of the forest results.
The economy continues to be dominated by primitive agriculture, hunting and fishing, and the gathering of various forest products.
