Lesson II – Effects of Deforestation Deforestation is the removal or destruction of large areas of forest or rainforest. Deforestation happens for many reasons‚ such as logging‚ agriculture‚ natural disasters‚ urbanization and mining. There are several ways to clear forest -- burning and clear-cutting the land are two methods. Although deforestation occurs worldwide‚ it’s a particularly critical issue in the Amazon rainforests of Brazil. There‚ the tropical forests‚ and the species of plants and

The slash and burn farming has to be done carefully because the soil can be washed away from a flood. Every step of the farming system

It occurs when waste is not disposed off properly‚ or can occur when humans throw chemicals unto the soil in the form of pesticides‚ insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface. Human actions have also caused many large areas of

invasion of industrial culture on their once simple lives. Soil erosion is another consequence of deforestation. Although these forests appear to be flourishing‚ the soils beneath are very poor. The problem is that once forests have been cut down‚ crucial nutrients are washed out of the soil completely. This leads to soil erosion. When there are no trees to keep the soil in place‚ it dries and cracks under the sun’s heat. If the soil temperature exceeds 25 degrees centigrade‚ explosive nutrient

The groups of farmers who were fortunate to acquire their land in the Northern and Central part of the Midwest were successful because the soil and climate was more favorable for the farming. The farmers who acquired their land on the Great Plains and further west often went bankrupt. This region had poor soil‚ a harsh climate‚ and lack of water supply. The railroad greatly benefited from this because they often bought the land from the bankrupt

versus environmental deterioration also has created a debate. Some economists argue that the on-site impact of soil erosion and other degradative processes are not severe enough to warrant implementing any action plan at a national or an international level. Land managers (farmers)‚ they argue‚ should take care of the restorative inputs needed to enhance productivity. Agronomists and soil scientists‚ on the other hand‚ argue that land is a non-renewable resource at a human time-scale and some adverse
