The direct human cost of Hurricane Katrina is so glaring, we’re only now becoming aware of the grave environmental consequences of the storm.
Consider this: according to the article linked above, coastal Louisiana produces a full thirty percent of this country’s domestic seafood, and that production has been severely impacted by the toxic aftermath of Katrina. The aftermath of the storm may cost shrimpers up to $540 million in sales over the coming year. There may be reason for optimism with respect to any long-term health hazards for residents of the city, but:
Additionally, the Coast Guard believes that seven million gallons of oil was spilled in the aftermath of Katrina, about two-thirds the quantity of the Exxon Valdez spill.The floodwater being pumped out of New Orleans is "a toxic gumbo like we've never seen," said John Rodgers of Clemson University. It's being pumped into Lake Pontchartrain, but Rodgers said he believes some of it will enter the Mississippi River as well.
Scientists will have to monitor river sediments for toxic metals and pesticides, which in the short term could kill fish and crustaceans or make them hazardous to eat, he said. Over a longer period, Rodgers said such contamination could diminish fish reproduction for several years.
Lots of work to do.
