how does animal waste effect the environment?
If there is massive runoff, water sources can be contanimated. However, this is highly exaggerated as a problem. Usually, local controls (pollution control at point sources...feedlots, dairy lots, hog pens...will control the problem. Some areas have gone to great lengths to prevent all runoff from streams, if one thinks on this, it is not a good policy. Nations need food, and these protein factories have to be located near water sources. Cows wont grow in the desert.
