Louisiana Ecological Harm Called Unprecedented

The environmental damage from hurricanes Katrina and Rita is unparalleled in its scope and variety, scientists say, with massive oil spills blanketing marshes, sediment smothering vast fishing grounds, and millions of gallons of raw sewage scattered in New Orleans and along the 400-mile Louisiana coast.
The catastrophe extends from the heart of the Big Easy, where streets, sidewalks, and floors are coated with a thick mud mixed with human waste, to the fringe of protective marshland, sugarcane fields, and citrus groves along the Gulf Coast that are beginning to die from the sea's salty surge. Thousands of acres seem to have been swallowed forever by the ocean.
"This is an unprecedented event in terms of devastation and scale," said Harry Roberts, director of the Louisiana State University's Coastal Studies Institute. He says it will take time to fully evaluate the storms' impact. "It's not like a spill on a river or a beach; you have small channels, canals, towns, levees. Everything here is complicated . . . and it's not a simple environment to assess damage in."
