Vanishing Louisiana theater

GANNETT NEWS SERVICE MULTIMEDIA

Louisiana is losing its productive and protective wetlands at a rate of 24 square miles per year to the Gulf of Mexico — almost 2,000 square miles since 1932. These animations, which were created from satellite imagery by the U.S. Geological Survey before last summer's hurricanes, show where the loss has occurred and where another 700 miles may vanish by 2050 if nothing is done.

The erosion is most pronounced in southeast Louisiana — the toe of state’s geographic boot — where the loss exposes New Orleans and its ports along with other populated areas to severe storm damage.
