Living in a modern society with more and more out-of-date but still useful puters, many people have to face such a troubling problem: How to deal with those old puters? Some old ones are put away in homes. Many more are just thrown out with the rubbish.
Don’t worry! Some panies are ing up with new ways to cut the number of old puters. Sony, Dell, Hewlett-Packard and other panies now agree to take back some old puters.
In some countries, there are laws about what to do with old puters. By law, puter panies will have to pay for collecting and recycling their used products. And 70% of puter waste must be recycled. The idea behind the laws is that puter panies themselves should pay the cost. That will encourage them to make puters that are easier and cheaper to repair and upgrade（升级）.
While many people are throwing away good puters, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old puters before sending them to schools, charities（慈善团体）and people who need them. In this way, we can turn one person's rubbish into someone else's useful things-and cut down on waste.
