Deforestation and its impact on the environment

Extracts from this document...


Deforestation This is when a large number of trees are cleared from areas of land for various reasons. The impact on the environment is extremely adverse, and there will be terrible consequences for future generations due to us cutting down, burning, or otherwise damaging the forests. In my essay, I am going to investigate the reasons as to why deforestation occurs and its impact on the environment. I will also look at any measures taken to minimise deforestation to prevent global destruction of rainforests, and ensure resources are available for future generations. There are many reasons accounting for deforestation despite its harmful effect on the environment. People need timber and wood from the trees to make paper, houses, and buildings due to urbanisation in some areas. It is used for commercial as well as industrial use. Trees may also have aesthetic, recreational, economical, historical, cultural and religious values to humans. Timber and other products of the forest are important economically both locally and as exports. Deforestation also provides employment to the people who harvest the wood. There are also many other products of the forest apart from wood as a result of deforestation which Herbalists, rubber tappers, hunters and collectors of fungi, nuts, bamboo and berries can utilise. ...read more.


The land becomes very dry and useless and the farmers move on to another area and deforest again. Another cause of deforestation is not the result of farmers but overseas companies looking for more rare and exotic woods which have increased in the last few years by 28%. Many Asian companies buy into logging companies in the Amazon with permits and begin to deforest in numerous amounts. There are various harmful consequences of deforestation. Hundreds of thousands of species are killed as they lose their habitats due to forest fires, cutting down of trees etc. deforestation also accelerates global warming because when the tree decomposes it releases the CO2 it absorbed when growing to make carbohydrates, fats and proteins. When a large number of trees are removed from an area, it causes soil erosion because there is no vegetation to reduce the impact of hard rain on the soil and there are no roots to hold the soil in place. It causes desertification (arable land is transformed to desert). Deforestation could also result in landslides and avalanches. Trees sustain freshwater supplies, so if they are cut down, it affects the availability of one of life's basic needs. ...read more.


IN rainforests, half of the rainfall is evaporated from the surfaces of soils and leaves or transpired by plants. The other half runs into streams and rivers and eventually reaching the ocean. When trees have been cut down, the recycling of water becomes inefficient leading to lower rainfall in the region. There are a few solutions to minimising the amount of deforestation that occurs. Replanting the clear cut areas to increase afforestation will be of help in the long term. More National parks/Reserves could be made. Alternative materials could be used instead of wood, such as plastic. The government should restrict the amount of land that can be deforested annually. Also. Using recycled materials will be of great help, as that means less trees need to be cut down to meet our demands. Deforestation has a major impact on the environment, such as rising sea levels, soil erosion, air pollution, loss of medicinal compounds in the forest, extinction of species, loss of ecotourism etc. A good way to prevent people from cutting or burning down trees is to improve their living conditions, so that they won't have to depend on deforestation for their livelihood. It must be reduced because thousands of species annually are being extinct. These species may have cures for cancer and AIDS. Aisha Hussain Page 1 08/05/2007 ...read more.
