Deforestation is the conversion of forested areas to non-forested land, for uses. ϒ Deforestation results from removal of trees without sufficient reforestation. ϒ The consequences of deforestation are largely unknown and the impacts not verified by sufficient scientific data leading to considerable debate amongst scientists. ϒ Deforestation is the permanent destruction of indigenous forests and woodlands. ϒ Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Forests must first be given credit for what they bring to global ecosystems and the quality of life that all species maintain. ϒ Tropical Rainforests presently give a place to call 50% - 90% of all organisms. ϒ Human race also benefits from what the trees give. ϒ The rainforests amplify and save lives. ϒ 25% of medicines come from the forests ϒ Trees improve the quality of the air Trees determine rainfall and replenish the atmosphere. ϒ Mother earth has given much responsibility to trees. Effects Deforestation presents multiple societal and environmental problems. ϒ The immediate and long-term consequences of global deforestation are almost certain to jeopardize life on Earth as we know it. ϒ Some of these consequences include: ϒ loss of biodiversity; ϒ the destruction of forest-based-societies ϒ climatic disruption. EROSION ϒ The underlying soils are very poor . ϒ essential nutrients are washed out of the soil all-together. ϒ about 80% of the soils in the humid tropics are acidic and infertile ϒ rainfall washes remaining nutrients into rivers. ϒ replanting trees will not necessarily help to solve the problems of deforestation. ϒ cultivation in the forest regions will be impossible. ϒ The soil erosion will lead to permanent impoverishment of huge land areas. ϒ The social impact of soil flooding
