Air Pollution
When people think of
air pollution, most immediately picture heavy smog drifting over cities and
industrial plants. This is the first and most evident form of air pollution,
but it’s not the only one. Let’s begin today’s discussion by defining the term
air pollution at a broader level. Air pollution in its most basic definition is
the introduction of harmful substances into the Earth’s atmosphere. These
substances linger and cause many adverse effects. As we know, humans and other
living creatures rely on the atmosphere for respiration. When air quality is
dampened by pollution, immediate and longer term consequences take place. In
addition, air pollution creates an imbalance in the natural gases that make up
our Earth’s atmosphere. These imbalances slowly aid in the depletion of the
Ozone layer, an essential region of the stratosphere that soaks up most of the
sun’s damaging ultraviolet (UV) rays. Pollution of the air affects the air that
humans and all other life forms breathe.
People around the world are suffering from respiratory and cardiac
problems, and diseases such as cancer affecting other organs of the body too.
Millions of people die each year around the world due to air pollution. To
protect our health from air pollution, proper measures should be taken. If not,
national health can never be saved. Our joint efforts and consciousness can
prevent air pollution.
