Deforestation is the main cause of soil erosion. Without plant cover, there will be an occurence of erosion that will sweep the land into rivers. Trees and their roots gives the soil a defense and refuge from the wind and rain. When forest are eradicated, it makes the land exposed and vulnerable of being washed away by elements. Logging exposes soil to rain splash which lossens soil particles. It erodes the soil making a more impermeable bare surface that increase runoff.
