Abstract
Wetlands help control pollution. They trap excess nutrients and chemical contaminants, and in some cases break them down into harmless substances. Studies at the Leopold Center for the study of sustainable agriculture at Iowa State University showed that a one-acre wetland could effectively purify the nitrate runoff from about 100 acres of cropland.
