     With alarming regularity, we read about oil tankers having accidents near land and the terrible

consequences of the oil spills(泄露) on people, nature, and the environment.

     Millions of dollars have been used in developing special chemicals to help dismiss the spills and to

clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals

are used, more damage is caused to the environment, especially to lives in the sea.

     Of all today's environmental disasters, an oil spill may actually be one of the least serious. Although oil

is poisonous, it is a natural material. In the end, it breaks down naturally. There are, of course, long-term

effects, but it is usually more serious in the short term.

     Nature by itself works better than chemical materials, but when there is a spill, we demand that

governments act immediately with as much hi-tech knowledge as possible. In 1967 the tanker Torrey

Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean.

If you go there today, you will find it hard to see any sign that it ever happened.

     Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that

we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the

biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.

     We should be thinking more about reducing our dependency on oil. Govern

-ments should be encouraging research into new technologies, such as cars run by solar power, electricity, hydrogen, and so on. Much of this research has, in the past, been held back by the oil, gas, and coal.

     If the world's millions of cars were 10% more efficient -and the industry could easily produce cars at

least twice as efficient, we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.
