THE CAUSES AND EFFECTS OF RAINFOREST DESTRUCTION
Nowadays, human are destroying the earth’s tropical rainfo
rests. About 80,000 squarekilometres are being destroyed every year. The rainforest destruction is the act of destroying athick forest in tropical parts of the world. There are a lot of causes and effects of the rainforestdestruction.The first cause of this phenomenon is logging. The commercial logging companies cutdown the trees that have been selected. The practice of the removal of trees from the forest eitherthrough the legal logging or illegal logging. However, large of rainforest are destroyed in orderto remove only a fews logs. The heavy machinery used to penetrate the forests and build roadscauses extensive damage. Trees are cut down and the soil is compacted by heavy machine and
thus decreasing the forest’s chance for regeneration.
Removing the selected trees from the forestcauses even further destruction, especially when it is carried out carelessly. It is believed that inmany South East Asian countries 'between 45-74% of trees remaining after logging have beensubstantially damaged or destroyed'. Therefore,
logging activities contribute to the rainforest’s
destruction.Secondly is the agriculture. Agriculture is a process of farming. The examples of theagriculture are shifting cultivation, intensive pastoral farming and so on.
Shifting cultivationhappens when the people who have moved into rainforest areas
and established small-scalefarming operations. Meanwhile, intensive pastoral farming is the branch of agriculturewhichconcerned with the raising of livestock.They have to clear the forest because th
necessities increased. When the land is cleared for agriculture, there are no longer any plants left
Destruction Of Rain Forest Essay
“In every sense, a standing rain forest supplies more economic wealth than if it were cleared … yet deforestation continues at an alarming rate.” (Tropical Rain Forest Coalition, 1996). Rain Forests have played a significant role in shaping modern biology. The destruction of the rain forests will determine the fate of all species humans plants and animals. Many people do not understand the long- term consequences of losing the earth’s rain forests. They have provided all living beings with many natural resources and medicines. Their complete destruction will affect all living conditions due to the influence they have on the climate around the world. Traditionally though, there are three major causes of the destruction to the rain forests: logging, farming and ranching.
For years rain forests have provided countries around the world with valuable resources, such as plants for medicine, energy, and minerals. First of all, in America, one fourth of all drugs prescribed have originated from rain forests. SP-303 is a compound extracted from a plant found in South America. Two products have been derived from this compound: Provir and Virend. Provir helps treat respiratory infections in children, while Virend is a topical ointment used to treat the herpes simplex virus. Another product from medicinal plants includes elements that treat addictive painkillers. (Refer to appendix 1) Secondly, in Brazil alone, the rain forest contains 45% of Brazil’s hydroelectric power (“In the Forest”). Thirdly, the soils of the tropical rain forest are typically nutrient poor; all of the nutrients are held in the living organisms. The warm, moist conditions in the forest are ideal for the decomposers breaking down the remains of dead organisms. This quick decay returns the carbon and oxygen in the decomposing material to the air, and returns nitrogen, phosphorous, calcium, and other minerals to the soil. (Refer to appendix 2) In the soil, a thick mat of plant roots and root almost immediately take up the minerals like fungi know as Mycorrhizae (“World Of Biology”). Any nutrients in the soil would be swiftly drifted away by the heavy rainfall. The soils in many areas of the tropical rain forests are laterite soils. These soils are reddish in colour and contain high levels of aluminium and iron, and resist leaching. Nutrients from decomposing organisms are found throughout the rain forest, not only in soil but also in trees. All of them are considered a backbone in today’s world. (Refer to appendix 3)
Moreover, the trees of the rain forest store things other than minerals such as carbon dioxide, in their roots, stems, branches and leaves. The trees also provide fresh air and release oxygen. This helps fight pollution and even gives out oxygen necessary for human life. Rain forests receive more than 200 days of rain per year, or as much as 240 inches of water. (Refer to appendix 4) They are characterised by...
