The U.S. lost an average of 80,000 acres of coastal wetlands from 2004 to 2009, according to the latest data published by federal agencies. More than 70 percent of the estimated loss came in the Gulf of Mexico; nationwide, most of the loss was blamed on development that incurred on freshwater wetlands.
"The losses of these vital wetlands were 25 percent greater than during the previous six years," NPR's Elizabeth Shogren reports for our Newscast unit. She also notes that the loss equals "about seven football fields every hour."
Since the 1930s, Louisiana has lost roughly as much land as makes up the state of Delaware.
"If you put the state of Delaware between New Orleans and the ocean, we wouldn't need any levees at all," says John Barry, vice president of the Southeast Louisiana Flood Protection Authority-East. "There is this large buffer of land that has disappeared, and that buffer makes New Orleans much more vulnerable to hurricanes."
