Air pollution is a very big problem in the United States. A large part
of air pollution comes from cars. The Environmental Protection Agency says,
"The most polluting activity an average person does everyday is drive their
car"(1 factsheet OMS-5). Most people probably aren't aware that they are
polluting the environment. Maybe if everyone knew how serious this pollution
problem is, they would find ways to reduce the pollution.
Most pollution that is released by cars comes from the exhaust, mainly
in the form of hydrocarbons(1 factsheet, OMS-5). Hydrocarbons are organic
compounds ,a combination of two or more elements, that contain only carbon and
hydrogen (2 factsheet, OMS-5). Hydrocarbons are released when fuel in the
engine burns partially. When hydrocarbons come in contact with sunlight they
form ground level ozone. Ground level ozone is a major ingredient in the
formation of smog. Ground level ozone is responsible for irritating eyes,
damaging lungs, and it complicating respiratory problems. Hydrocarbons aren't
the only pollutants released through car exhaust.
Two more pollutants released through car exhaust are carbon monoxide and
nitrogen oxide. The first reduces the flow of oxygen to the bloodstream, and
could harm people with heart disease. Nitrogen oxide is formed when a car
engine gets hot. It contains chemicals that aid in the formation of ground
level ozone as well as acid rain (2 factsheet, OMS-5). Acid rain destroys the
outsides of buildings, statues, etc. Acid rain can also contaminate drinking
water, damage vegetation, and destroy sealife. These two pollutants are two of
the most dangerous pollutants released through car exhaust. If these two
pollutants were cut down just a little bit our planet would be a safer place to
Carbon dioxide is another gas released through exhaust emissions. It
isn't dangerous directly to humans, but it is considered to be a "green house
gas." A "greenhouse gas" is a gas... [continues]
