Wetlands to the Horizon

The grasses and animals living in marshes help to filter water and stabilize shorelines, along with providing habitat for a variety of mammals, fish, shellfish and amphibians and a haven for migratory waterfowl. Along with supporting rich ecosystems, Louisiana wetlands are nurseries for fish and other seafood that support fisheries in the state, the second largest in the United States. But the wetlands are disappearing from both natural and human causes, including hurricanes. Find out how many football field-sized pieces of wetland were lost in Hurricane Katrina.
