| Summary: | Ocean acidification is having a deleterious effect on the shellfish that live in Maine's coastal waters. Oyster grower Bill Mook has observed first-hand the changes in his oysters' behavior when their water gets too acidic. Mark Green, a professor of marine science at St. Joseph's College and an oyster grower himself, points out that the change in ocean acidity is happening at an alarmingly fast rate. Scientists and fishermen worry about how marine ecosystems will be able to respond to this stress. They worry, too, about the general public's relative ignorance of the imminent threat.
