Right answer: There is enough oxygen available for people’s lungs to function normally.
Air pollution is due to a mixture of solid particles and gases in the air. This is caused by various polluting factors, among which are carbon monoxide emissions from automobiles, nitrogen oxides, chemical compounds from factories, dust and ozone.
In this context, the inhalation of these toxic components increases the chances of having health problems, even death. However, when these conditions are improved by removing pollutants and taking actions to purify the air; the life quality of the people who breathe it improves as well.
Therefore, there is enough oxygen available for people’s lungs to function normally.
