TANGIER, Va. - Tidal waters flood yards in this small Chesapeake Bay island fishing community here September 16, 2016. The community of roughly 470 residents are experiencing the impacts of sea level rise, erosion and land subsidence. Scientists estimate the island may become uninhabitable over the next 25 to 50 years if something is not done to help keep the island above water. (U.S. Army photo/Patrick Bloodgood)
