Animal Waste

The problems with hog factories actually start at the loading dock. Because corn and other hog feeds are not farmed extensively in North Carolina, to feed the state's 10 million hogs, factory farms must bring in train car after train car of grain from the Midwest.

This grain is loaded with nitrogen and phosphorous, which the hogs eat, digest, and excrete. Only a small percentage of the grain is converted into meat. The remainder is turned into hog waste and disposed of in North Carolina's environment.

This means much of the nitrogen and phosphorus stored in hog feed ends up in hog excrement and ends up in North Carolina's soil, air, and water.
