Every time an old computer breaks down, it needs to be dealt with safely. What is worse, at present, broken computer parts are usually buried. It may be hundreds of years before they are really gone in the earth.Many places in China are polluted by ewaste. Guiyu in Guangdong Province is one of them. This town is named as “the ewaste capital of the world〞. It has to deal with 1.5 million kilograms of ewaste each year, from which it makes 75 million yuan. But it comes at a cost. Many of the poisons in ewaste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu are badly polluted.Luckily, the Chinese government wants the country to change the situation. China has passed a new environmental protection law, the strictest one we have ever had. Computer companies like Lenovo and Dell are asked to take back their old computers.
