“There has been much debate in the past 20 months over protecting Louisiana from another lethal hurricane, but nearly all of it has been conducted without any real understanding of the geological context. Congress and the Bush administration need to recognize six facts that define the national interest. Fact 1: The Gulf of Mexico once reached north to Cape Girardeau, Mo. But the Mississippi River carries such an enormous sediment load that, combined with a falling sea level, it deposited enough sediment to create 35,000 square miles of land from Cape Girardeau to the present mouth of the river. This river-created land includes the entire coast, complete with barrier islands, stretching from Mississippi to Texas. But four human interventions have interfered with this natural process; three of them that benefit the rest of the country have dramatically increased the hurricane threat to the Gulf Coast.”
