The Causes of Deforestation in the Amazon Rain Forest Essay -- Exposit

The Causes of disforestation in the virago Rain tone The amazon Rain Forest crosses several national boundaries in South America, although the majority of it is located in brazil-nut tree. It covers over 3,562,000 acres, making it the largest in the world. But glob on the wholey, over 138,600 acres of precipitate forest are lost each year to deforestation, 50,000 of those in Brazil alone (Holdsforth), and the worlds rain forests are quickly disappearing. Deforestation in the Amazon occurs primarily for three reasons clear- bring downting, fragmentation, and edge effects. The term deforestation refers to the clear-cutting of large sections of base or original-growth forest, which causes the prejudice of native species of plant and animal life. This clearing of farming is mainly due to agricultural needs, such as farming and oxen ranching, but similarly occurs to support logging and mining companies. The effect of the loss of forest is most obvious in the loss of native species. Eugene Ng, of the Hong Kong technological Institute, explains that the destruction of habitat forces species out of areas, or causes them to die. Other factors, according to Ng, moreover restrict their range, exposing them to disease and predators. Deforestation does not occur neatly. Fragmentation also weakens the rain forest. As large sections of rain forest are cut down by farmers, ranchers, and loggers, those plant and animal species are left to die. If all deforestation occurred along the outside boundaries of the forest, then some of the species could move deeper into the Amazon to survive. But as Mason Skold and Bill Myer explain, fragmentation produces areas of less than speed of light square kilometers which are surrounded by d... ...in Forest and to protect the species who stand firm there must take into account how deforestation occurs.
