Have you ever heard of e-waste （electronic waste，电子垃圾），which can be produced every day？How do you deal with your computers，MP4players and mobile phones when they're broken or you want a new one？
Most people just throw them away．With the development of electronic industry，e-waste pollution has become a serious problem．According to the United Nations （联合国），in 2014，people around the world produced 41.8million tons of e-waste and only recycled 6.5million tons．The US was the biggest waster，producing 7.1million tons．China came second，with 6million tons．
It's important to pay attention to e-waste．It can either be valuable or harmful，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 is famous for its products iphone，iPad，Apple Watch and so on．The company now recycles 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 buy longer lasting （持久的） electronic products．If you have unwanted electronics，find a new home for them．You can also take computers and phones to see if companies offer recycling programs．
