The soil which we see at the surface of Earth actually consists of many layers among them the most fertile is the top layer which lets trees and plant grow with all the necessary nutrients and also helps them to grow. Soil erosion is the phenomenon which results in moving away the fertile top layer of the soil and gets us exposed to the rocky unfertile layer. This is generally caused either due to extreme natural condition such as cyclone or flood which takes along with it the top layer of the soil and another major reason which is responsible for soil erosion is human activities such as deforestation.
Deforestation is the practice of cutting down trees for human needs such as product manufacturing or clearing land for building establishments. Cutting down trees result in loosening the soil particles as because there is no more root to bind and hold the soil particles together firmly. Processes such as building concrete roads all over results in uprooting the green grass which also helps in binding the soil together.
Soil erosion is a serious problem which needs to be taken proper care of, we should plant more and more trees in order to ensure that the upper fertile layer remains intact.
