The harbor is their oyster

This Saturday afternoon, the Massachusetts Oyster Cracker Project will be placing oysters in Boston Harbor, at the mouth of the Charles River.

The goal isn't to give the Union Oyster House a new supply of slurpable food, but to create a natural filtration system for the harbor:

Charles river flow is 300 million gallons per day. Ten small beds of oysters 225 feet square (less than a football field) could cleanse this volume on a daily basis.

Would this happen instantaneously? No. Would every gallon of flow be filtered? No. But can these Oysters improve the situation? Absolutely.
