The atmosphere is a complex naturally occurring system consisting of a mixture of various gases. This system is
vital for sustenance of life-cycle on the earth. The term air pollution is used, when different health damaging substances
like particulate matter, organic particles, or other toxic resources are introduced into earth's environment, triggering
illness and disease, allergic disorders and even demise, not only to human being but potential harm to other living
entities like wildlife, food-stuff garners and other constituents of the natural human and animal habitats. Air pollution
may come from man-made sources, as a result of rapid industrialization or deforestation and so forth, or from natural
sources. Considering these findings, air pollution (both indoor and outdoor) was ranked as top-most dangerous global
threat to life of any kind on earth.
