E lectronic waste
Introduction: Electronic waste also called E- waste. It is including electrical equipment and some electrical apparatus element that people throw it away and will never use it again . The most common things about electronic waste including mobile phone, television, air-condition and refrigerator.
T he electronic waste is not very good because it will bring with some pollution such as air pollution. T he most common method to solve electronic waste is put it in a very high temperature , but after that it will bring air pollution to destroy the environment, M any animals will take in the waste air and as the same as the human. T he electronic waste not only brings the air pollution but also bring with some heavy metal. I ncluding Pb Au Ag Cd Hg and many others. F rom that time this heavy metals can easy enter into the ground water, and the ground water is value for everyone animal in this world, if the heavy metal in the water it is bad for them to live. S o all in all, it is get in the way of human to live in a safety and comfortable environ ment. I n order to get better environment, develop the science is very important!
N owadays, scientist uses some method to deal with this problem. T he first method is cremation, put the electronic waste in a very high temperature and separate some valuable things. I t is the most common way to separate it but it will bring much pollution like air pollution. T his method will destroy the environment so it is not a very good way. T he second method is Mechanical engineering. T his method is use the machine to extrusion and incision the electronic waste. I t is a physics method and is very cheap, but it will cause much noise pollution and air pollution. S o it is also not a very good way to solve it. T he third method is Chemical treatment; the most common method is to put the electronic waste into the acid or base. A fter few hours it will also separate the valuable things and it is more refine. B ut every time after the refine it will produce much rubbish liquid. I t will destroy the water and also destroy the environment. I n the end these three methods are useful because it can help people to solve the problem that deal with the big number of electronic waste, but it will cause many another problems. Here are some solutions to solve this problem. T he first one is
R ecycle. A ccording to the international environment group, the number of 2011 people all over the world throws the electronic waste reach the 2100000 ton. Only after three years the number of 2014 people all over the world reaches approximate 7100000 ton. Nowadays electronic waste all over the world increase faster and the number become bigger and bigger. F rom that date prove that there was an increase in the electronic. And American and China are the biggest waste of electronic in the world from 2011 to 2014.every year the electronic waste was increase, so if people can do a good job in recycle it will save many material to make a same but new one. S o recycle is very important and it is also a good way to deal with the electronic waste. T he second one is make better product quality. Electronic waste is something people throw it and never use it again, when people throw it means that it has something wrong. S o if the government or the company can make some better product quality
T hat can let people to use it for a long time, it is also can decrease the number of the electronic because people can use one thing for a long time and need not to change the new one, so the old one will not be electronic waste soon. T he third one is to improve the education , on a one side, if people want to product some better quality things must have a good education or it will very hard to come up with a good idea to develop the quality of electronic machine. O n an other side, education can also teach children to protect the environment because without earth, without everything !
