Exercise 7. Read the passage about Air Pollution and find the answers to the questions below.

AIR POLLUTION

We are nowadays becoming more aware of pollution matters that affect dramatically our lives, especially there is growing concern about air pollution. There are some reasons that lead to this kind of pollution.

Firstly, the development of industrial zones, factories and building construction areas is producing a large amount of dust and poisonous air. Especially in developing countries, people don’t pay much attention to the air treatment process which makes the air pollution even worse.

         Secondly, because of the increasing urbanization, it can be easily seen that there is always a lot of traffic in rush hour and dust on the road these days. The smoke from vehicles and manufacturing exhaust increases the amount of carbon dioxide in the air which makes us feel really hard to breathe. The consequences are very bad.

Smog and dust can do serious harm to our health, especially our lungs. We have thousands of asthma and adult respiratory distress cases each year which raise concern about the air quality. Moreover, acid rain is becoming more and more popular which damages crops and fields. Many people believe that air pollution is also causing global warming and it is difficult to improve the air without the efforts of all countries around the world.
