A new report from the Chesapeake Bay Foundation finds pollution and overfishing are responsible for choking off the blue crabs’ food supply and destroying their habitat. The group is calling on the Environmental Protection Agency to bring forward a new plan to enforce the Clean Water Act. The foundation says the crabs are suffering as well as people. Many watermen are losing their jobs as the crabbing industry declines. The Bay’s blue crab population plummeted from 791-million in 1990 to 260-million in 2007.
