In 1993, New York State ordered stores
to charge a deposit on beverage (饮料) containers. Within a year, consumers had
returned millions of aluminum cans and glass and plastic bottles. Plenty of

products, but because few could figure out what to do with the plastic, much of
it wound up buried in landfills (垃圾填埋场). The problem was not limited to New
York. Unfortunately, there were too few uses for second-hand plastic. Today, one out of five plastic soda bottles is recycled (回收利用) in the United States.
