| | |  | | |  Although soil may seem plentiful, it can be polluted and depleted by natural and human activities. Examine sources of soil pollution and discover some of the efforts taken to prevent this, such the construction of sanitary landfills and the long-term storage of hazardous waste. Visit Love Canal, an area dramatically affected by soil pollution, and see the state of that community today. Although soil erosion is natural and necessary, human activity can hasten and magnify this process. Learn how "America's Bread Basket" was transformed into the "Dust Bowl" during the 1930s, and see what farming methods have been implemented as result. Finally, travel to Shirley Plantation in Virginia, and observe how several ambitious projects have reclaimed degraded land to transform potential wastelands into valuable farmlands. Soil is much more than dirt beneath our feet. It is an essential component of life on Earth. A teacher's guide is included and available online.
