The Chesapeake Bay Foundation drops-off 75 bushels of recycled oyster shells for an environmental restoration event at Joint Base Langley-Eustis, Va., June 8, 2017. During the event, students of Booker Elementary School placed oyster shells near the Langley Air Force Base marina so that approximately 2,000 young oysters could attach to them and build a new ecosystem.
