Defining air pollution is necessary because it affects us right here at home, and we may not be able to see or taste it, but we can all feel its effects. Air pollution is the existence of certain substances in the air, which are harmful to human health and cause harm to objects, or affect the environment in some way. There are various kinds of air pollutants, including chemical substances, gases, and microbial molecules.
Most air pollution comes from combustion of fossil fuels and industrial emissions. A good example is vehicle exhausts, factory emissions, fuel fumes, aerosols, smoke, and dust. One important thing to remember is that some hazardous gases cannot be seen and cannot be smelled. They are called greenhouse gases, and they include carbon dioxide, methane, ozone, chlorine, and many others.
We all know that air pollution causes damage to our environment. This damage is done through the depletion of the ozone layer and global warming. Ozone layer depletion results in clouds that become overcast, thus preventing the growth of plants that need oxygen for photosynthesis. Global warming causes sea levels to rise, melting ice, glacier retreat, and increases humidity. As if that were not enough to worry about, the pollutants in the air also pose serious threats to human health, especially to those who suffer from respiratory diseases.
There have been efforts to define air pollution. The Environmental Protection Agency (EPA) was created by the Clean Air Act of 1970. This legislation aims to reduce air pollution and to protect human health and the environment. Among its functions are the regulation of air quality, the prevention of air pollution due to toxic wastes, and the protection of the ozone layer. Another important function is to define the sources of air pollution so that we can avoid or mitigate such emissions. Each product has to meet certain standards when it comes to manufacturing.
Air Pollution Facts
One way to define air pollution is to look at the different sources of it. When you take a walk on the streets, you will notice many air-borne particles floating around. These include pollens, dust, dirt, smoke, steam, dust, and noise. Each of these has a source and a level of effect, depending on its size and composition.
As defined, air pollution is caused by the inhalation of air pollutants. These may consist of gases, vapors, solid particulates, oxides, pesticides, and some compounds in natural air. It is an air pollution problem that affects us all.
If you want to reduce this menace, there are a number of things you can do. One is to use a purifier that functions as an air pollution filter, removing most of these harmful particles from the air. Another option is to change your vehicle to an energy efficient one. The latter reduces the strain on the car engine that causes air pollution.
If you wish to help the cause of reducing air pollution in the city, then you should buy a hybrid or a clean car. Buy the one that does not emit more than 50% of its energy in gasses. Run your car on water if possible. Use an air conditioner to keep the temperature low outside. Do all these things to help lessen air pollution.
This definition of air pollution makes it a very frightening concept. But unfortunately, it is a reality today. There is not much you can do to avoid it. Even if you live in a well equipped house with all the required technology inside, the pollution in the air is unavoidable. There is no such thing as pure air. Sooner or later, it will affect your health.
In The End
But before we get to the definition, let us look at how it starts off. Once an air pollution is formed, it begins off with a tiny particle, which eventually turns into a larger more dangerous one as time goes by. The end result of all this is the dreaded smog.
Hence, it is really important that we have a constant reminder about this definition of air pollution. It is our responsibility to protect ourselves from this menace. Be careful when you go out. Know what you are breathing in. Avoid places where there is high air pollution.
