In some locations, massive portions of sand have been faraway from beaches to be used in making concrete. New Moore Island, for instance, was a small, uninhabited island in the Bay of Bengal. Both India and Bangladesh claimed the island, which was little more than a strip of sandy beach. In March 2010, rising sea ranges drowned the island fully. For years, coastal erosion threatened the Cape Hatteras Lighthouse, on Hatteras Island in the U.S. state of North Carolina. The Cape Hatteras Lighthouse is the tallest lighthouse within the United States. For more than one hundred years, it has warned ships of the low-mendacity sandbars and islands generally known as the Outer Banks.
