About forty five years ago the enviormentalists won a great victory. They succeeded in stopping yearly the baby seal hunt that had been conducted off the coast of New England every winter. The sight of burly white men clubbing baby seals into bloody pulps was too much for America to bear. The hunt stopped, the seals prospered and grew in numbers. The sharks noticed the increased food supply and expanded their feeding territories to include Cape Cod beaches and the people that use them. So it goes.
