Land erosion is the process by which soil and rock are worn away from the Earth's surface, often due to natural forces like wind and water. This can lead to the loss of fertile land, making it difficult for plants to grow and affecting local ecosystems. Human activities, such as deforestation and construction, can accelerate land erosion by removing vegetation that holds soil in place. When heavy rains or strong winds occur, the exposed soil is more likely to wash or blow away, leading to further degradation of the land and potential environmental issues.
