The Mississippi River had been controlled over the years to stop the annual floods with hundreds of miles of levees and dams. As a result sediments that were naturally brought down to replenish the land, were cut off. Gradually Louisiana started to lose its coast and today it has the highest rate of coastal land loss in North America. An area the size of Wembley stadium is lost to the sea every 20 minutes. On another thread, the loss of land was blamed on Big Oil. Ha.

The problem is two fold. The sediment from the river is one thing. But also in the marshland huge areas were cut to make sort of river highways for oild exploration. This compunded the problem and is a part of it.
