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 the developing
countries, people don't pay much attention to the air treatment process that 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 and especially our lungs. We have thousands of asthma and adult respiratory distress cases
each year which raise concern about the air quality. Moreover, acid rains are becoming more and
more popular which damage 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.
