 It's a pattern the scientists have seen for years. Restoring New York Harbor's oyster glory is a hit-or-miss endeavor. The scientists are collaborating with the Billion Oyster Project, which has planted 122 million of them in waters surrounding the city. Data shows about half of those oysters die, and so far, none of the oysters are reproducing on their own. One here, dead. Dead, dead. It's alive. It's alive.
