context1: The area of Nantucket Island proper is 47.8 sq mi(123.8 km2). The triangular region of <strong>ocean</strong> between Nantucket, Martha's Vineyard and Cape Cod, is Nantucket Sound. The highest point on the island is Folger Hill which stands above <strong>sea</strong> level.
context2: Many animals that live on or in the <strong>sea</strong> consume flotsam by mistake, as it often looks similar to their natural prey. Plastic debris, when bulky or tangled, is difficult to pass, and may become permanently lodged in the digestive tracts of these animals, blocking the passage of food and causing death through starvation or infection. Tiny floating particles also resemble zooplankton, which can lead filter feeders to consume them and cause them to enter the <strong>ocean</strong> food chain.
