Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn’t enough information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases.

The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as other children and they are clumsy when they use their hands.

There are other long-term effects of pollution. If the gases in the atmosphere continue to increase, the earth’s climate may become warmer. A lot of the ice near the Poles may melt and may cause serious floods.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

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 -
