Wetlands
Many states in the Unites States of America have lost a high percentage of their wetland. "California has lost 91 percent of its limited wetlands; in the wetland-rich Great lakes states, 50 to 90 percent are drained" (Mayda 29). California has lost a high percentage of its wetlands.
The California wetlands were altered because of agricultural and urban usage. The water that surrounded the wetlands was takes from the wetland areas and used for something else. California had about 3 to 5 million acres of wetland in the past. Now, California has about 450,000 acres of wetland which means that California lost about 85 to 90 percent of the wetland, that's a huge lost.(http://ceres.ca.gov/ceres/calweb/wetlands/wetland_past.html).
Wetlands are beneficial for many reasons which can be seen in this illustration. Wetlands filters pollution and support wildlife. It's a shame that California has lost about 90 percent of its wetlands.

A wetlands is a transitional zone between dry land and water . Wetlands include swamps, bogs, and marshes. "Wetlands filter impurities before surface water reaches the groundwater. However, many wetlands have been destroyed or impaired, which has increased groundwater pollution" (Mayda 29).
In American History, wetlands have been drained in order to be used for agricultural or residential purposes. In 1950, the wetlands were declared to be "useful" because of their ecological importance. The removal of wetlands caused an increase in water pollution and it destroyed the coastal buffer zones that protected the inland areas (Mayda 29).
