The world itself is becoming
much smaller by using modern traffic and modern communication means (通信設(shè)備). Life today is much easier than it was
hundreds of years ago, but it has brought new problems. One of the biggest is
pollution(污染). To pollute means to make
things dirty. Pollution comes in many ways. We see it, smell it, drink it and
even hear it.
Man has been polluting the
earth. The more people, the more pollution. Many years ago, the problem was not
so serious because there were not so many people. When the land was used up or
the river was dirty in a place, men 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 to all living things in the world, but it is not only
one kind of pollution. Water pollution kills our fish and pollutes our drinking
water. Noise pollution makes us become angry more easily. ?
Many countries are making
rules (法規(guī)) to fight pollution. They
stop the people from burning coal(煤)
in houses and factories in the city, and from blowing dirty smoke into the air.
? The pollution of SO2
is now the most dangerous problem of air pollution. It is caused (引起)by heavy traffic. It is certain 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
keep careful of the rise in pollution at the same time.
