Ben and his classmates are watching a DVD about the environment. A long time ago , most towns and villages were very small . The number of people 　36 lived in every country was much smaller than it is today, too. There was 37 heavy industry . People did not use chemicals .There were no motor vehicles and there were no factories . So there was very 38 polution .

Sadly , our environment is much dirtier than 　39 was in the past . This is a 　40 , because the best way for us to be healthy is to live in a clean environment .

　　 The air and water are much dirtier than they 　 41 be . The chemical factories and cars

42 terrible gas .The water 　43 by chemicals from the factories and ships .This means we are destroying our home little by little .

In the DVD we will try to find ways to 　44 our environment cleaner and find ways to stop future pollution .We hope you will learn 　45 you can to help make the world cleaner and healthier.
