people don’t know how to deal with them. Many old puters are put away. Many more are simply thrown away as rubbish. Finally, some panies are thinking of ways to bring down the number of old puters. Sony has agreed to help recycle old Sony products(产品 ). Dell, Hewlett Packard and other panies now also take back some old puters of their own brands. In some countries, laws have been passed, too. Computer panies have to pay for collecting and recycling their used products. And 70% of the puter waste must be recycled. The idea behind the laws is that puter panies themselves should pay for the cost. That will encourage them to make puters which are easier and cheaper to repair and upgrade(升级 ). Yet many people are throwing away good puters, while others cannot afford them at all. Hundreds of anizations are working on this problem. They collect and repair old puters. Some also teach others how to repair puters. These repaired puters then go to schools, charities(慈善团体 ) or people who need them.
