Have you ever heard of e-waste (electric waste),which can be produced every day?How do you deal with your computers 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 about 41.8 million tons of e-waste and only recycled about 6.5 million tons.The US was the biggest waster,producing about 7.1 million tons.China came second,with about 6 million 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(有毒的) chemicals can get into the earth or air,affecting the environment and people’s health.
Some companies now recycle people’s used products in China when they are buying new ones.The companies will test and repair the used ones and sell them at lower prices.To help reduce e-waste,we can also take computers and phones to see if companies offer recycling programmes.
