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 you 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.
Pollution has been known to cause allergies, disease, damage to crops, and in extreme cases, even death.
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.
As the Ozone depletes, the rate of global warming increases. If enough air pollution clutters our environment, it creates the danger of more rapid deterioration of the Ozone layer.
