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 easily. Air pollution is the most serious kind of pollution. It is bad for all living things in the world.
Many countries are making rules to fight pollution. We need to do many other things. We should put waste things in the dustbins instead of 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 pollution.
