The world itself is becoming much smaller byusing modern traffic and modern communication means （通讯设备）.Life today is mucheasier than it was hundreds of years ago, but it has brought new problems. Oneof the biggest is pollution. To pollute means to make things dirty. Pollutioncomes in many ways. We see it, smell it, drink it and even hear it.

Man has been polluting the earth. The morepeople, the more pollution. Many years ago, the problem was not so seriousbecause there were not so many people. When the land was used up or the riverwas 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’sbad for all living things in the world, but it is not the only one kind ofpollution. Water pollution kills our fish and pollutes our drinking water. Noisepollution makes us angry more easily.

Many countries are making rules to fightpollution. They stop people from burning coal in houses and factories in thecity, and from putting dirty smoke into the air.
