LOUISIANA BAYOUS<br />
The bayous are disappearing. Since the 1930s, the coast of Louisiana has lost 1,900 square miles of marshes and coastal wetlands. This is an area the size of Delaware that has been swallowed up by the Gulf of Mexico. Despite recent efforts to reduce the erosion of the bayou, Louisiana still loses about an acre of land every 33 minutes. That results in a loss of 25 square miles per year. Levees have funneled marsh-building sediment into the ocean; engineers have cut 8,000 miles of canals through the bayous to help the petroleum industry, all of which contribute to the faster erosion of the bayous.
