问题     Rubbish dumps throughout the industrial world are nearly full, heralding a crisis for city authorities as they look at alternative ways of dealing with the global garbage crisis.
    That problem is peculiar to fast-moving, wealthy societies, which increasingly demand more packaged goods. In New York State alone, residents have doubled their demand for packaged goods in the past thirty years. And the situation is not expected to ease, not least because of social trends. As more women transfer their production and management skills to commercial enterprises, demand for convenience products in the home continues to grow, says a report published by the Washington-based World Watch Institute.
    The only solution for a nation which now spends more on wrapping food than it pays farmers to produce it, is recycling on a grand scale for commercial as well as conservation reasons.
    The Institute wants multi-layered dustbins to be distributed to households, and people to be obliged to separate their waste into four categories: organic, glass and metals; paper; plastics and miscellaneous. It also believes it can only be a matter of time before such bins have to be made compulsory.
   Cynthia Pollock, the author of the report, entitled "Mining Urban Wastes: The Potential for Recycling", points out that "consumers and policy makers are just beginning to realize that there is not real ’away’ for throwaway".
    Pollock believes that recycling is the only alternative. "Although household wastes are usually thrown out with little regard for their remaining value, a list of the world’s discards would reveal a wealth of materials." And it is not just food; "Simply recovering the print run of the Sunday edition of the New York Times would leave 75,000 trees standing and reduce the energy used per ton of paper by up to three-quarters."
The reason why the World Watch Institute wants multi-layered dustbins to be made compulsory is______.

选项 A、to make people keep organic and inorganic waste separate
B、that they can be distributed to households
C、to facilitate the recycling of rubbish
D、that time may be saved in collecting rubbish

答案C

解析 文中第四、五段“Cynthia Pollock...points out that......for throwaway.”指强制使用多层垃圾箱对垃圾进行分类,是为给垃圾再循环提供便利条件。因此,C项符合题意。
