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 problems 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 hard to all the 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(被子) over a city.This kind of quilt is called smog.
Many countries are making rules to flight pollution.Factories must now clean their water before it is poured away,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 ,less pollution will be made .Rules are not enough to solve the problems .Every person must help to fight against pollution.
