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

Most Americans find it hard to think what life would be without a car．However，some have realized the serious problem caused by cars．The polluted air is harmful and dangerous to health．

One way to get rid of the polluted air is to design a new car．That is what several large car factories are trying to do．But to build the new car is easier said than done．Progress in this field has been slow．

Another way is to replace the car engine with something else．Engineers are working on some new cars．Many makers believe that it will take years to develop a practical model that pleases people．

To prevent the world from being polluted by cars，we'll have to make some changes．Americans，for example，have to cut down the number of their cars．They are encouraged  to travel and go to work by bike．Riding a bike is thought to help keep the air clean．

But this change does not come easily．A large number of workers may find themselves with no jobs if a car factory closes down．And the problem of air would become less important than that of unemployment．

Although ears have brought us a better life，they have also brought us new problems．

Environmental pollution is the biggest problem for human being today. We all know that the environment includes the earth,water, plants and animals.If they are polluted or hurt, oour life can also be harmed.

It is true that more and more trees are being cutting down. The earth is becoming warmer. If the problem continues, the world will become a desert, and people will have no place to live.

The smoke produced by cars, factories and homes is polluting the air. Poisonous gas is letting off into the air , too. The polluted air make people sick.

Then there is the sound pollution. Our world is not quiet, even at night, because of the noise made by cars and people’s daily life. Too much noise has a bad influence on our hearing. It has been reported that many people in a village near an airport have lost their hearing because of the noise made by planes.

The water and the earth we are living on have also been polluted. The rubbish people throw away and the waste water poured by factories make the water and the soil polluted. When we drink dirty water or eat crops planted on polluted soil, we can get sick easily.

Just imagine what will happen if this continues. I ‘m sure it won’t be a pleasant result.

A report from the United Nations said that around 60 million people across the world, with 80% of them in Asia, are drinking polluted water. Some 4,500 children die every day because of polluted water.

A report showed that environmental problems kill 3 million children under five years old each year, making them one of the key contributors(捐助者) in more than 10 million child deaths worldwise each year.

Dangerous factors include indoor and outdoor air pollution, water pollution, lack of good hygiene facilities and poor ecological (生态学) systems(系统) , it said.

Another study showed that parents and experts from seven countries including the United States, India and Nigeria, regarded pollution as the biggest threat (威胁)to children’s natural living environment.

Many parents say that children today are being brought up with fewer blue skies than when they were little kids.

Mrs. Green tries to teach her daughter Susan by setting a personal example. She picks out recyclable waste and uses the water from the washing machine to wash the toilet.

Chinese children mostly learn about environmental protection in school.

Some non-governmental organizations and child centers also teach kids to protect the environment. More parents have become aware of it. Family is now playing a more important role,” says a Chinese official.

Vera Lehmann, an expert from Germany says many Chinese are increasingly aware of polluted. “I was surprised to find how much schools in China are willing to contribute to educating the children on environment,” Lehmann said. “There has been a big change between now and ten years ago when I first traveled here.”
