The impacts of deforestation in the tropical rainforest.

Deforestation is having an effect on all tropical rainforests. This is not just negative effects but also some very positive effects from the deforestation of the rainforests. From deforestation there are many problems that can be caused by this, environmental, social, economic and political issues all from the destruction of the rainforests across the world. There has been dramatic deforestation across the world for some time now and many of the Earths natural forests have been cleared or degraded so that they can be used for other purposes. Tropical forests are being destroyed at an ever-increasing rate. Estimates of the extent and rate of loss vary, but it appears that nearly half of the world's tropical forests already have been lost, and the remainder will all but disappear in the next two to three decades. The loss is incalculable. These forests provide habitat for an estimated half of the world's plant and animal species, provide water and fuel for much of the world's population, and influence regional and global climate. Commercial logging, clearance for agriculture, ranching, and fuel gathering are all responsible for the destruction. Solutions include the development of alternative fuel wood supplies through fuel wood plantations, the regulation of logging, and a consensus as to the value of forest conservation over commercial development.

When trees are removed, particularly from mountainous areas, topsoil is exposed and may be washed away by rain. The resulting erosion can clog streams with silt, harm fish populations and degrade water quality. The use of terracing and the planting of ground cover crops can reduce this problem. Deforestation is a major contributor to the habitat loss that continues to threaten endangered species across the planet. For example, the rate of destruction of the Amazonian rainforest increased by 40% between 2001 and 2002. More than 25,000 sq km were cleared in a year, mainly for farming. That represents an ...
