Most people sell their productive services for money and then use the money to buy goods and services that are produced by a large number of other people. Some people are engaged in making machines that will be used to make other machines or tools with which to manufacture goods.This process of specialization and division of labor results in a tremendously greater output of goods and services than would be possible without it. It also makes us extremely dependent upon other people both to buy the goods or services that we help to produce and to supply the goods or services for us to buy that we do not produce for ourselves. This interdependence contributes to the plexity and severity of many problems arising out of changes in economic activity.

Not only would a return to selfsufficiency mean a greatly reduced standard of living。 it is doubtful if the present population could even be maintained under such a system.66.

So more and more are driving to work every in their own cars. To many city dwellers, cars have bee a necessity. But too many cars in the street also create problems. Traffic congestions, accidents and air pollution are the three most obvious problems that acpany a sharp increase of cars. We often get caught in heavy traffic during the rush hours, when it takes a long time to move forward even an inch. And thousands of people die while a greater number are injured, some crippled for life, in traffic accidents every year. If we want to enjoy our cars in safety, we had better follow the traffic rules carefully. Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars pletely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.
