MIDDLE GROUND, LA - APRIL 19: A shrimp boat trolls for its catch on April 19, 2011 near Middle Ground in southern Louisiana. A year after the BP oil spill coated Gulf coast beaches and marshes, BP claims that most of the oil has been removed. Louisiana Wildlife and Fisheries says, however, that much of the coastal cleaning has been superficial, as the oil has seeped into the soil, killing marshes and further eroding the state's damaged Mississippi Delta ecosystem.
