In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a general.
Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic
goods represented by precious metals was relatively small in comparison to traditional waste, the concentration(含量) of gold and other precious metal was higher in so-called e-waste than in naturally occurring minerals.
Electronic wastes also contain many poisonous metals. Even when the machine… and the harmful metals removed, the recycled process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.
Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging it came in. Many wastes produced in the producing process are harmful as well.
