The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even eat it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problems was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollutions. It is caused by heavy traffic. We are sure that if there are fewer people driving there will be less air pollution.

The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.

Do you know why different animals or pests have their special colours? Colours in them seem to be mainly used to protect themselves.

Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colurs with the changes of the colours of crops .When crops are green, locusts look green .But as the harvest time comes, locusts change into the same brown colour as crops have .Some other pests whose colours are different from plants are easily found and eaten by others .So they have to hide themselves for lives and appear only at night.

If you study the animals’ life, you’ll find the main use of colours is to protect themselves .Bears, lions and other animals move quietly through forests .They cannot be easily seen by hunters because their colours are much like the trees.

Colours are useful not only on the land , but also in the sea .A kind of fish in the sea can give out a kind of black liquid(液体)when the fish face danger. The liquid spreads over quickly, so they cannot be found by their enemies and can quickly swim away. That is why they can live safely though they are not strong at all.
