Wind erosion strips off topsoil and transports nutrients downwind while weakening soil’s stabilizing forces – Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Soil erosion is the displacement of the upper layer of soil by various agents, particularly water, wind, plants, animals and humans.
