A small town named Bundanoon in Australia has decided to stop the sale of bottled water(瓶装水). They say that bottled water can cause environmental problems. Too many resources(资源) are used to make bottled water. When people finish drinking the water, the bottles will be thrown away and go into dustbins. So they require local people in the town to stop buying bottled water and use tap water to drink. Visitors are encouraged to get water from water stations in the main streets, and fill the water in bottles that can be used again. The decision has been supported(支持) by all the shopkeepers in the town. Bundanoon is the world’s first town that has got its shop selling bottled water. Probably we should follow the example. Let’s stop buying bottled water and use tap water！
