The remaining 10% is all we will ever have. Deforestation is a significant issueof our time and must be taken seriously if we want to protect our remainingforests. The definition of deforestation by the Random House Dictionary of theEnglish Language is “to divest or clear of forests or trees” and we must stopdeforestation to save our planet.

My intent on writing this essay is toenlighten the reader about the facts on deforestation and to express my opinionsabout deforestation. There are approximately 3 400 million hectares of forests in the world,nearly 25% of the world’s land area. Close to 58% of the forests are found inthe temperate/boreal regions and 42% in the tropics. For about a millennium,people have benefited from the forests.

Forest products range from simplefuelwood and building poles to sophisticated natural medicines, and from high-tech wood based manufactures to paper products. Environmental benefits includewater flow control, soil conservation, and atmospheric influences. Brazil’sAmozonia contains half of the world’s tropical rain forests. The forests cover aregion 10 times the size of Texas. Only about 10% of Brazil’s rain forests havebeen cut to date, but cutting goes on at an uncontrollable rate. Since pre-agricultural times the world’s forests have declined one fifthfrom 4 to 3 billion hectares.

Temperate forests have lost 35% of their area,subtropical woody savannas and deciduous forests have lost 25% and ever-greenforests which are now under the most pressure have lost the least area, 6%,because they were inaccessible and sparsely populated. Now with new technology,such as satellites systems, low altitude photography and side looking radar,scientists can now figure that the world is losing about 20. 4 million hectaresof tropical forests annually and if these figures are not reduced, we will loseall of our tropical forests in about 50 years. It has been suggested that thehigh deforestation rates are caused partly by the fact that the new surveys aremore accurate and thus reveal old deforestation rates that have not beendetected with older methods. At first there was concern only among foresters about deforestation butnow the public has created organizations such as Green Peace to help increaseawareness and reduce deforestation. The Food and Agriculture Organization orF.

A. O, has worked mainly within the forest community to find new and better waysto manage the forests. Also, in 1985 there was the introduction of the TropicalForestry Action Plan or T. F. A.

P. This plan involved the F. A. O, United Nationsdevelopment programs, the World Bank, other development agencies, severaltropical country governments, and several government organizations.

Togetherthey developed a new strategy. More than 60 countries have decided to preparenational forestry action plans to manage their forests. Tropical deforestation has various direct causes: The permanentconversion of forests to agricultural land, logging, demand for fuelwood, forestfires and drought. Slash and burn clearing is the single greatest cause oftropical rain forest destruction world wide.

Air pollution is also a majorthreat to the forests in the northern hemisphere and is expected to increase. Reduced growth, defoliation and eventual death occur in most affected forests. From 1850 to 1980 the greatest forest losses occurred in North America and theMiddle East (-60%), South Asia (-43%) and China (-39%). The highest rates ofdeforestation per year are now in South America (1. 3%) and Asia (0.

9%). Over the last two decades the world became interested in the loss oftropical forests as a result of expanding agriculture, ranching and grazing,fuelwood collection and timber exportation. The consequences are increased soilerosion, irregular stream flow, climate change and loss of biodiversity. Deforestation is second only to the burning of fossil fuels as a human source ofatmospheric carbon dioxide.

Almost all carbon releases from deforestationoriginate in the tropics. Global estimates of the amount of carbon given offannually by deforestation is 2. 8 billion metric tons. Deforestation accounts forabout 33% of the annual emissions of carbon dioxide by humans. In 1987 11countries were responsible for about 82% of this net carbon release: Brazil,Indonesia, Colombia, Cote d’Ivoire, Thailand, Laos, Nigeria, Vietnam,Philippines, Myanmar and India.During 1987 when there was intense land clearingby fire in Brazil’s Amazon, more than 1.2 million metric tons of carbon arebelieved to have been released.To save .
