Impacts of deforestation

Deforestation not just impacted the forest biodiversity. Deforestation also impacted the soil. Forest soil layer was have high nutrition that created by natural composting activity. When the vegetation on the area not exists anymore, soils will disable to receive the rain that will make erosion and flood. Deforestation will removed this fertile layer, soils then become very thin and poor in nutrients. When an area is completely deforested for farming, the farmer typically burns the trees and vegetation to create a fertilizing layer of ash. After this slash-and-burn deforestation, the nutrient reservoir is lost, flooding and erosion rates are high, and soils often become unable to support crops in just a few years. If the area is then turned into cattle pasture, the ground may become compacted as well, slowing down or preventing forest recovery.


people make their livings through subsistence agriculture, hunting and gathering, or through low-impact harvesting of forest products like rubber or nuts. Deforestation large scale by loggers or “outside people” could make social conflict. People will lose their land that will affect their live.


Forest make important rule to the water cycle. The forest will receive the rain well. Water evaporates from the soil and vegetation, condenses into clouds, and falls again as rain in a perpetual self-watering cycle. The evaporation also cools the Earth’s surface. Deforestation will remove this cycle and increased the earth temperature.
