    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 taster than traditional garbage as a whole.

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 total waste,the concentration(含量)of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.

Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling 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(包装)it came in.Many wastes produced in the producing process are harmful as well.

The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling.

In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive(动机)for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place?

Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or towns be responsible for paying to deal with the bubble wrap(气泡垫)that encased your television?

From the governments' point of view,a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.

A.the weight of e-goods is rather small

B.natural minerals contain more precious metals

Freedom and Responsibility

Freedom’s challenge in the Digital Age is a serious topic. We are facing today a strange new world and we are all wondering what we are going to do with it.

Some 2,500 years ago Greece discovered freedom. Before that there was no freedom. There were great civilizations, splendid empires, but no freedom anywhere. Egypt and Babylon were both tyrannies ,  one very powerful man ruling over helpless masses.

In Greece, in Athens (雅典), a little city in a little country, there were no helpless masses. And Athenians willingly obeyed the written laws which they themselves passed, and the unwritten, which must be obeyed if free men live together. They must show each other kindness and pity and the many qualities without which life would be very painful unless one chose to live alone in the desert.The Athenians never thought that a man was free if he could do what he wanted. A man was free if he was self-controlled. To make yourself obey what you approved was freedom. They were saved from looking at their lives as their own private affair. Each one felt responsible for the welfare of Athens, not because it was forced on him from the outside, but because the city was his pride and his safety. The essential belief of the first free government in the world was liberty for all men who could control themselves and would take responsibility for the state.

But discovering freedom is not like discovering computers. It cannot be discovered once for all. If people do not prize it, and work for it, it will go. Constant watch is its price. Athens changed. It was a change that took place without being noticed though it was of the extreme importance, a spiritual change which affected the whole state. It had been the Athenian’ s pride and joy to give to their city. That they could get material benefits from her never entered their minds. There had to be a complete change of attitude before they could look at the city as an employer who paid her citizens for doing her work. Now instead of men giving to the state, the state was to give to them. What the people wanted was a government which would provide a comfortable life for them; and with this as the primary object, ideas of freedom and self-reliance and responsibility were neglected to the point of disappearing. Athens was more and more looked on as a cooperative business possessed of great wealth in which all citizens had a right to share.

Athens reached the point when the freedom she really wanted was freedom from responsibility. There could be only one result. If men insisted on being free from the burden of self-dependence and responsibility for the common good, they would cease to be free. Responsibility is the price every man must pay for freedom. It is to be had on no other terms. Athens, the Athens of Ancient Greece, refused responsibility; she reached the end of freedom and was never to have it again. But, “the excellent becomes the permanent”, Aristotle said. Athens lost freedom forever, but freedom was not lost forever for the world. A great American, James Madison, referred to: “The capacity (能力) of mankind for self-government.” No doubt he had not an idea that he was speaking Greek. Athens was not in the farthest background of his mind, but once man has a great and good idea, it is never completely lost. The Digital Age cannot destroy it. Somehow in this or that man’s thought such an idea lives though unconsidered by the world of action. One can never be sure that it is not on the point of breaking out into action only sure that it will do so sometime.
