People today are exposed to various air pollution. Therefore, they are affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution. One of the main causes of air pollution is vehicle traffic. Cars, buses, trucks, motorcycles, scooters and trailers are run on fuel. Burning fuel cars leads to exhaustion of toxic compounds including toxic gases as well as particulate matter. Hazardous gases that are part of exhaust fumes include hydrocarbons, nitrous oxides, carbon monoxide and sulfur dioxide.

Plants also contribute to air pollution. Toxic fumes and smoke generated by factories are released into the air thus causing air pollution.

Similarly, burning fossil fuels such as coal, as well as burning firewood for cooking and farm waste leads to toxic fumes that pollute the air. Burning waste also creates toxic fumes.

Air pollution affects the air that people and all other life forms breathe. People around the world are suffering from respiratory and cardiovascular problems and diseases like cancer affect other organs of the body. Millions of people die every year around the world due to air pollution.

In the past, people didn't think children will be ones building a country. However, in the future, this view will changed. Teenagers are the next generation, who will be controlling and running the world someday. As a result, teenagers play an important role in society. What they do, what they accomplish, what they are exposed to has every effect on, not only our personal future, but the future of society as a whole. If they develop well, study hard and are always creative, their community will be getting more and more modern. Clearly, every generation grows up in a completely distinct world. The prosperity of a country in the future depends on the teenager generation. As teenagers, we need to have faith and power within ourselves. We need to have initiative. We are in charge of the future generations. If we don’t make a change ourselves, how will improvements in society occur?
