There are many kinds of pollution. Air, water, and land can be polluted. Some pollution is caused by nature, such as floods, forest fires, and volcanoes. People are the major cause of pollution. We pollute the air with our cars, homes, and factories. Smoke from factories and car exhaust makes the air looks gray and smoggy. Some people cannot go outside when the air is very bad! We pollute the water by dumping garbage and chemicals in the water. Plants and animals die because of the pollution in the water. We pollute the soil with chemicals and garbage. We harm the land by cutting down trees in the forest, especially to build roads and new houses without careful planning and thinking.
The only way to save our environment is to think about pollution. How can you stop or limit pollution? How do we protect our environment? Conservation is one way to protect our environment. Conservation is the wise use and protection of our environment. We can control water pollution by not producing as much waste and by proper disposal of sewage and garbage. We can take care of recreation land by cleaning up after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air pollution.
Recycling is a type of conservation. Recycling is reusing items over again or in a new way. Recycling can help US conserve our natural resources so they will last many more years.
A. Find the word in bold in the passage that means:
1. the protection of the natural environment Conversation
2. have a bad effect on something dumping
3. a large amount of water covering an area that is usually dry floods
4. sharing a car ride with other people carpooling
5. waste gases that come out of an engine exhaust
6. the process of making air, water, soil, etc. dirty pollution

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. _3__ Pollution is the poisoning of the land, sea and air.
B. __5_ 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. __1_ 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. _6__ 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. _4__ 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. _2__ 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.
