The oil slick is still 20 miles away from some of Lousiana's most delicate wetlands. Still, fisherman in Breton Sound aren't willing to take any chances. They've been laying out and monitoring boom around the clock. But here's the problem—there isn't enough of the stuff to go around. The Breton Sound area has millions of acres of broken islands and marshlands. So the best thing these fisherman can do with a limited amount of boom is strategically place it at key inlets. The Department of Wildlife and Fisheries is hoping that defense will keep oil out of the inner marshlands. They're still working on plans to set up barriers to protect wildlife at some of those isolated habitats.
