Rainforest depletion caused by logging thesis statement
With desperate need for land for agricultural, industrial and most importantly urban needs to contain cities and their, a direct action that we have come to recognize as Deforestation occurs. Deforestation in simple term means the felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. Over the last century the forest cover around the globe has been greatly compromised, leaving the green cover down to an all time low of about 85 per cent. 8 million hectares) of forest are lost each year. Deforestation can also be seen as removal of forests leading to several imbalances ecologically and environmentally. What makes deforestation alarming is the immediate and long term effects it is bound to inflict if continued at the current pace.
Some predictions state that the of the world will be destroyed completely if deforestation continues at its current pace. Deforestation or clearance occurs due to several reasons, to get an overview we could include the need of money, both in terms of profitability as well as providing for one s family in most scenarios, along with lack of or no forest laws, need for land space for housing etc among a long list of other uses. Mainly blamed on agricultural or pastoral use, farmers fell trees for increasing space for cultivation and/or as fodder land for grazing and surviving live stock. The whole concept of slash and burn agriculture, is used to indicate this same process where farmers employ the above chain of actions for their purposes. 6. Agricultural Activities: As earlier mentioned in the overview, agricultural activities are one of the major factors affecting deforestation.

Due to overgrowing demand for food products, huge amount of tress are fell down to grow crops and for cattle gazing. (June 7559) During the last two decades, agricultural expansion, logging, development, and other human activities caused the deforestation of more than 675,555 square kilometers each year. In contrast, an area only one-tenth that size was regained due to reforestation efforts and natural re-growth. 6 This is the continuation of an historical process that has left the world with less than half of its original forests. While population growth and density are unquestionably related to forest cover trends, there is no simple way to describe or predict that association. Nonetheless, important patterns are beginning to develop from the many studies that have been undertaken and the evolving debate around them. 7 In a number of more developed countries, such as the United States, China and Russia, forest cover has been recovering for some time after extensive earlier deforestation.
8From the deforestation studies to date, a few generalizations can be made. At extremely low population densities (less than one to two persons per square kilometer), it is possible to maintain large amounts of forest intact in areas where the population can be sustained primarily through the harvesting of non-timber forest products rather than by agriculture. 9 However, even in sparsely inhabited areas, external forces such as demand for timber or cattle in other parts of the country or world can lead to deforestation that is not closely related to local population growth. This has been the case in parts of the Brazilian Amazon. 6 The poorer the soil quality, the lower the agricultural production per hectare, and the more land per capita is likely to be cleared. In Central America, population density and loss of forest cover are closely related at many scales: at the regional and national level, and in local areas inside and near forest reserves, such as the Maya Biosphere Reserve in Guatemala.
