      Have you ever heard of e-waste (electric waste,电子垃圾) ,which can be produced every day? How do you deal with your computers,MP4 players and mobile phones when they’re broken or you want a new one?

      Most people just throw them away. With the development of electric industry,e-waste pollution has become a serious problem. According to the United Nations? in 2014,people around the world produced 41. 8 million tons of e-waste and only recycled 6. 5  million tons. The US was the biggest waster,producing 7. 1 million tons. China came second,with 6 million tons.

      It's important to pay attention to e-waste. It can either be valuable or harmful (有害的) , depending on how we deal with it. E-waste is a valuable urban mine (城市矿藏) . The value of the metals,like gold and silver in the waste around the world,is amazing. And the metals can be reused. But if people throw them away,the toxic chemicals (有毒化学物质) can get into the earth or air,affecting the environment and people's health.

      Apple,for example,now recycle people's used products in China when they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce (减少) e-waste,we can also take computers and phones to see if companies offer recycling programs.
