4/ How can industry help? 

5/ What cause pollution? 

6/ What about air pollution?  

A. ___ Pollution is the poisoning of the land, sea and air. 

B. ___ Mainly industry and transport. If you go to any city, you will see too many factories, too many  cars with not enough people in them, and not enough public transport. 

C. ___ Factories and vehicles produce waste which goes into the air and rivers and spreads all over  the land. Poisons in the waste build up over the years and harm trees, plants, animals, and people. D. ___ Waste gases build up in the air, and dissolve into raindrops, forming a weak acid. This "acid  rain" can fall far away from the country which produced it, killing trees in forests and fish in lakes and  rivers. 

E. ___ If companies clean their waste gases before releasing them into the atmosphere, there'll be  much less air pollution and no acid rain. But this can be expensive and it needs all the world's companies  to do it. 

F. ___ Cars pollute the atmosphere. Walk, cycle and use public transport as much as possible. Only  use your car when you really need to, and use unleaded petrol if you can - lead is one of the most dangerous  ingredients in petrol. Join us, and help us to campaign for cleaner air for everybody.
