Air
Pollution
By: Emily Zhong
You open the window and
take a fresh, clean breath of air. But really how clean is that air? Pollution
happens every day, every hour, every minute. From plastic to gas, we pollute
the Earth whether we know it or not. One of the major types of pollution is air
pollution. And this spikes the question, what is pollution?
Pollution is the
introduction of any matter or any form of energy to an environment at a rate
faster than it can be dispersed or stored in some harmless state. Air pollution
is the release of pollutants into the air that is detrimental to human health
and the planet. While there are natural causes of air pollution like volcanic
ashes, forest fires, and hot springs, there are also ways we pollute the very air
we breathe. Some ways we pollute the air are the use of fossil fuels,
electricity, and transportation. And our actions could have momentous
consequences if we continue on with this.
There are approximately
4.2 million deaths every year as a result of exposure to ambient air pollution.
Approximately just eight percent of people worldwide breathe air that meets WHO
(World Health Organization) standards. That means a staggering 92 percent of
people breathe polluted air. A toxic environment could be perilous. At least
one out of four deaths reported worldwide is caused by a toxic environment.
Your body relies on the air you breathe, and poor air can cause damage to the
lungs and other organs.
The burning of fossil
fuels like coal and oil produces 2/3 of the SO2 (sulfur dioxide) in the air.
And this gas can irritate the eyes and lungs and makes the rain acidic. Acid
rain kills aquatic life and also damages buildings. The burning of fossil fuels
also produces CO (carbon monoxide), which is an odorless, colorless gas that
interferes with our bloodstream and could cause heart damage or even death.
Deforestation is also a contributor to air pollution. The loss of trees affects
the air by reducing the amount of oxygen and increasing the amount of carbon
dioxide, as well as contributing to global warming.
Some other causes of air
pollution are greenhouse gases, smog and soot. Greenhouse gases trap the earth’s
heat in the atmosphere, leading to warmer temperatures. Possible consequences
include the melting of polar ice caps, and this could lead to an increase in
sea level, precipitation and severe weather events like hurricanes. Smog can
aggravate the eyes, throat and harm the lungs. This is substantially worse for
children, people who spend time outside, and senior citizens. It’s even worse
for people who have asthma or allergies. These additional pollutants only
intensify their symptoms and can trigger asthma attacks.
Some ways we can reduce
air pollution is using less gasoline and making smart choices about
transportation. You can walk, ride a bike, or take public transportation. And
for driving, you could choose cars that get better miles per gallon of gas or
choose an electric car. You can also investigate your power provider options,
like using solar or wind energy.
It is time we paid
attention to better the air quality since air pollution has resulted
predominantly from the things that benefit people. We can all help in our own
way. It may cause small inconveniences, but in the long run, if everyone unites
to solve the problem, we can make a significant change to protect the
environment as well as human health.
