BRING SCIENCE HOME Can Plants Help Slow Soil Erosion? Soil is a surprisingly valuable resource. But it doesn't always stick around. Learn how a few plants can help save it from being washed away by water.  Credit: George Retseck Perhaps you try to save water. Maybe you already reduce, reuse and recycle. But did you ever consider conserving soil? Perhaps you haven't, but soil erosion—the wearing away of soil by water, wind and other natural forces—can be a major ecological problem. Productive farmlands can disappear as nutrient-rich topsoil in fields washes away when heavy rains hit them. Waterways can then become polluted as pesticides and fertilizers wash into them. Even human life and property are jeopardized when soil erosion causes mud- and landslides. The economic cost of soil erosion is estimated to be several billion dollars every year for the U.S. alone. This is a serious problem; can you help solve it? Do this activity and learn how to help save the soil with nothing more than a few plants!
