How do human activities most significantly contribute to soil erosion?

Human activities significantly contribute to soil erosion primarily through practices such as deforestation and overgrazing. When trees are removed in deforestation, the protective cover that vegetation provides is lost, exposing the soil to wind and water erosion. Without roots to anchor it, the soil becomes more easily eroded. Similarly, overgrazing by livestock can strip the land of vegetation, leading to a lack of cover that helps hold the soil in place. This results in soil being washed or blown away, reducing soil fertility and leading to desertification in severe cases. Engaging in these practices disrupts the natural balance of the ecosystem, contributing to increased soil erosion rates significantly more than other options like promoting vegetation growth or sustainable agricultural practices.
