Polluted air can caused many of health problems!! Yes, this
is fact. Moreover, polluted air could affect the life around us like animals,
plants and even the water surfaces in very harmful way.
How we pollute our air?
The manufactures and smoke sources cause the most of the
air pollution by producing toxic gases like benzene and vinyl chloride. Those
gases particles stuck on air and cause real respiratory diseases like asthma and
internal organ damages like brain or nerves system when people breath them in
addition of some other symptoms such as eyes and nose burning.
On the other side, some chemical gases are damaging our
planet. The Chlorofluorocarbons (CFCs) is the main cause of
the ozone layer depletion or “hole” (the layer in the stratosphere that surrounded the earth and protect it
from the dangerous ultraviolet radiation that
come from the sun). The Chlorofluorocarbons
can be founded in the cooling machines like A/Cs and refrigerator. The ozone layer started to disappear already
over some regions in the earth and this thing reflected on the living beings on
the planet. The range of the skin cancers has increased in addition of the eyes
problems. Furthermore, the forests, animals, crops and water bodies are damaged
by this environmental defect.
All those problems lead to big economic losses. When the air
pollution impacts the agriculture, the income from this sector will decrease.
Moreover, the countries governments will spend money to find cures for the
diseases that caused by air pollution and also the workers will lose days in
work which means less financial gain.
The Congress in 1970 made an initiative by establishing the
Environmental Protection Agency (EPA) and gave the federal government the green
light to fix the problem and stop this harm. The EPA and civil society and also
the factories cooperate to decrease the air pollution in the United States. The
Clean Air Act that passed by the Congress has succeed to change some of the bad
habits that harm our air and environment.
