DVD1574
Environmental Science for Students provides a fascinating look at some of the most important environmental issues of our time. 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 it. 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 implimented as a result. Through contrasting examples like Love Canal and Shirley Plantation, see how issues of soil pollution and degradation have been addressed. Soil is much more than dirt beneath our feet.
