Pollution
Hundreds of years ago,life was much harder than it is today. People didn't have modern
machines. There was no modern medicine,either.
Life today has brought new problems. One of
the biggest is pollution. Water pollution has made our rivers and lakes dirty. It
kills our fish and pollutes our drinking water. Noise pollution makes us talk
louder and become angry more easily. Air pollution is the most serious kind of
pollution. It's bad to all living things in the world.
Cars,planes and
factories all pollute our air every day. Sometimes the polluted air is so thick
that it is like a quilt over a city. This kind of quilt is called haze (雾霾).
Many countries are making rules to fight
against pollution. Factories must now clean their water before it is thrown
away,and they mustn't blow dirty smoke into the air.
We need to do many other things. We can put
waste things in the dustbin and not throw it on the ground. We can go to work
by bus or with our friends in the same car. If there are fewer people driving,there will be less pollution.
Rules are not enough. Every person must
help to fight against pollution.
