Human Impact on Wetlands
     As of the mid-1980s the lower 48 states held claim to 103.3 million acres of wetlands. Alaska had 170 to 190 million, and Hawaii had 52,000. It is certain that these figures have decreased since the last tally of wetland acreage in the United States. It is estimated by the EPA that on nonfederal lands alone, anywhere from 70 to 90 thousand acres of wetlands are lost each year to progress and development. In addition to the complete loss of wetlands in some areas, other areas have had trouble maintaining the stability of their wetlands. Many wetland systems are no longer able to function in all the ways formerly possible. Many factors are contributing to the loss of wetlands. The following is a list of the human and natural impacts on the stability of wetlands.
