Today, air pollution has become a distressing reality in most parts of the world. Air pollution is a chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earth's ecosystems.
There are almost as many types of air pollution as there are potential solutions. No matter what type of air purification system you're looking for, you should know that there is not one product on the market today that can solve every problem. Plants and trees, nature’s natural mechanism to purify the air that we breathe, have been successfully doing the job of air-purification for us for the last thousands of years. Our symbiotic relationship with them ensures that they cleanse our air of carbon dioxide, which they use for their survival, in exchange for oxygen, which is a necessity for our survival.
Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Enforced air quality standards, like the Clean Air Act in the United States, have reduced the presence of some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are actually mobile sources, principally the automobile. There are many available air pollution control technologies and urban planning strategies available to reduce air pollution; however, worldwide costs of addressing the issue are high. The most immediate method of improving air quality would be the use of bioethanol fuel, biodiesel, solar energy, and hybrid vehicle technologies.
