However, these shells are no longer thrown into waste containers. 1 In the U.S., shells cast aside in restaurants and other businesses are being collected, cleaned and thrown back into waterways. 2 One of the latest projects on oysters (牡蛎) takes place in Atlantic City, New Jersey. The shells were put into the state’s Mullica River and help form new or expanded oyster groups. Free-floating baby oysters connect to the shells and grow on them. 3 It has also helped eateries save money on dealing with their shells, according to Scott Stueber, a fisheries biologist with the Department of Environmental Protection. 4 In nature, oysters are cleaners. One adult oyster can remove pollutants from about 190 liters of water a day. So oysters can improve water quality. Oyster groups also are being planted along some coastlines to strengthen shores. Besides, oyster reefs can protect shorelines. Such reefs can also be homes for sea creatures and provide food for humans. Communities, environmental groups and governments around the world have had oyster reefs recycled and replanted in recent years. 5 For example, each year in Maryland, about 70 cubic meters of recycled shells are turned into oyster groups. Since 2009, the Harte Research Institute at Texas A&M University has collected about 800,000 kilograms of shells and rebuilt about 100,000 square meters of oyster reefs. A.
