3Deforestation means cutting down the trees to a large extent be it forests, any barren land or trees we see on our way to school every day. Natural forests are being destructed to use the land for cultivation, building houses, factories, logging, making space for cattle grazing, extraction of oil, mining, construction of dams or to obtain wood for making furniture and using it as fuel.
Forest wood has been an essential need for us since the time of civilization and still continues to be the main source for many uses in our day to day life. Trees help to maintain the water cycle and give shelter to the organisms. It takes place in an area that is densely populated by trees and is mostly observed in a forest like the Amazon rainforest. Forests cover almost 30% of the earth’s land.
The extinction of the forest cover affects the biodiversity which in turn threaten peoples lives. Shrinking of the forests cause wide-reaching problems like soil erosion, fewer crops, flooding, water cycle disruption, greenhouse gas emissions, changes in the climatic conditions, and loss of biodiversity.
