阅读理解。 A small town in southwest Britain is banning (禁止) plastic bags in an attempt to help the environment and cut waste－a step that environmentalists believe is a first for Europe. Shopkeepers in Mod bury population 1,500, agreed to stop handing out disposable plastic bags to customers on Saturday. They said paper sacks and cloth carrier bags would be offered instead. Last month, San Franciso became the first U.S. city to ban plastic grocery bags. Internationally, laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland, where governments either tax shoppers who use them or fine companies that hand them out. Bangladesh already bans them, and so do at least 30 remote Alaskan villages. Mod bury, about 225 miles southwest of London, has also declared a bag ammesty (宽限期), allowing local people to hand in plastic bags that have piled up at home. They will be sent for a recveling. The Mod bury ban was the idea of Rebecca Hosking, who saw the effect of bags on manne life while working in the Pacific as a wildlife camerawoman. She said response (反应) in the town so far had been 'really positive'. 'Mod bury is quite an old-fashioned town and a lot of people have wicker baskets to go out shopping anyway,' Hosking told Sky News Television. The World watch Institute, an environmental research agency, states that 100 billion plastic bags are thrown away each year in the United States alone.
