Hoping Katrina provides a boost to restoration efforts - By LEE BOWMAN, Scripps Howard News Service
The levees, canals and channels built after floods devastated New Orleans in 1927 had, until this week, mostly done a good job of protecting a city that lies as much as 20 feet below sea level. But they had stopped a 7,000-year-old cycle of flooding and meandering that allowed the Mississippi River to replenish the delta and build barrier islands.
'The sad irony is that the levees ... have the unintended consequence of laying waste to the very wetlands that are the state's greatest natural protection,' said Valsin Marmillion, a spokesman for America's Wetland: Campaign to Save Coastal Louisiana, a coalition promoting wetland restoration.
