The following paragraph on “Air Pollution”
Air is a vital element of the environment. When it contains
the elements which are hazardous for human health, it is called polluted. Air
is important because, without it we cannot live. It is essential for human
life. Air is polluted in many ways. Air pollution can be of two types- indoor
and outdoor. The air indoor under certain circumstances can be polluted to a
hazardous level. Radon is released from rocks and soils that carry radium. If
its decay is inhaled it leads to lung damage. Asbestos fibers also are a
potential source of lung cancer. A single burning cigarette releases particles
to the order of 1012. On the other hand smoke emitted by trucks, buses and
other vehicles causes air pollution. We should take proper steps to control air
pollution. To improve our life style, we should not use any harmful elements.
We should give up smoking.
