3. Examples and sources of air pollutant
• Air pollution occurs when contaminating agents are

nor do they happen often. The unnatural pollutants that
humans release into the air generate concern because of
the health problems they create and the massive damage
they inflict on the ozone and environment.
• The five common causes of air pollution come from daily
human activities and natural occurrences; some issues that
arise as a result of continuous air pollution are health
problems in humans, acid rain, a depleted ozone layer and
heavy smog.
