Our factories and homes burn coal and oil. Every year, we have forest fires somewhere. Many scientists believe that the climate is changing.

The earth will perhaps be warmer by about 7 degrees centigrade at the South Pole(南极)and the North Pole. The ice will melt. The sea level will rise by about 7 meters. As a result, water will cover cities like London, Tokyo and New York. Some ports(港口）and towns along the coasts will disappear under the water.

Some other scientists think that the dust, smoke and pollution from coal, wood and

oil fires will block out the sunrays. Then the earth will become colder and much ice will cover Europe and North America.

People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
