A group of travelers were having dinner in a restaurant. While they were eating fish, they began to tell stories about finding valuable stones inside fish.

An old man, who had listened to their conversation quietly, said at last,”Now I’m going to tell you a true story of my own. When I was young, I worked in a large company in London. As is usual with other young people, I fell in love with a pretty girl. Soon we were engaged. Two months before our marriage, I was suddenly sent to Edinburgh on business. My stay was a bit longer than I had expected. At last my work was done and I left for home. Before I left Edinburgh, I bought a nice diamond ring for my sweet-heart. On my way to London, I was looking through a newspaper. It was then that I learned of my sweet-heart’s getting married to another man. I was so sad that I threw the diamond ring into the water. A few days later, when I was eating fish, I bit on something very hard. What do you think it was?

“The diamond ring,” shouted his friends. “No,” said the old man sadly, It was a fish bone.

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans work at putting together the pars of cars, driving trucks, building roads or filling cars and trucks with gas. Americans won't live without cars!

Most Americans would find it hard to think what life would look like without cars. However, some have realized the serious problems of the air pollution that is caused by the car. The polluted air becomes poisonous and dangerous to health.

One way to get rid of the polluted air is to build a car that does not pollute. That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean.

But this change does not come easily -a large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.

Although cars have led us to a better life, they have also brought us new problems.
