In Mark Kurlansky's 2005 book about New York City and oysters, The Big Oyster: History on the Half Shell, the author suggested that given the improved environmental conditions of New York Bay, perhaps the time is ripe to start replanting the oyster fields that used to carpet the underwater surface. The City and environmentalists are now undertaking a project to replant oyster beds in the bay, not for harvesting, but as natural, or soft, anti-pollution filters.
