    How does erosion affect the environment?

    A:

    Erosion affects the environment by stripping away top soil on agricultural land, damaging delicate coastal areas, causing health problems in humans and contaminating bodies of water with sediment that can harm plant and animal life. Erosion damages farm land by removing nutrient-rich soil needed to grow plants and by exposing lower-quality soil. It also damages crops and causes greater runoff of needed water.
