Deforestation Essay, Research Paper

Deforestation Deforestation is the act of cutting down and clearing out trees in large amounts. This is occurring in many areas of the world, specifically in the rain forests of South America and Africa. It is very profitable to be in the tree business and that is the reason many people seek to be hired in this area of business rather then any other. Even with the positive aspect of the wages, deforestation is damaging the Earth, her animals and her natural resources. One example of the negative effects caused by the cutting down of trees is that it will eventually lead to a lack of oxygen in the air. Trees recycle dirty air that people have breathed in and out, exposing the carbon-dioxide. The trees feed on the CO2 and in turn release fresh oxygen into the air. It is a cycle that will drastically change if a large percentage of trees on the Earth are destroyed. Another example of a negative effect cause by deforestation is many species are killed, and with concern to the

rainforest, many endangered species have no hope to survive. The rain forest houses more animal species then everywhere else in the world combined. When deforestation occurs, animals homes are destroyed and they are with them. The third negative effect that occurs when deforestation is allowed is that plants are cut down, burned and destroyed to make way for the machinery. In the rain forest there have been many plants that proved useful in medical procedures and even plants that cure such things as cancer or reduce the white blood-cell counts. If we destroy the rain forest we may be destroying our opportunity to find cures to diseases we have yet to cure. These examples clearly illustrate the idea that the deforestation of rain forests are unnecessary and should be unnecessary. Not only could it destroy the Earth s plants and wildlife, but in the end could show our fate if we continue to cut down the trees. People may die because of the lack of medications that might have been found in the acres of Africa and South America. Hopefully, sooner then later, people realize that the deforestation of these areas in unneeded and will cease.
