Question 1. Choose ONE appropriate question in the box to each paragraph below:

1/ How do industry and transport cause pollution?
2/ How can I help?
3/ What is the pollution?
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.
