Air Pollution:
The main cause of air pollution is the smoke releases from road-vehicles,
industrial chimneys etc. Thus the amount of carbon dioxide increased and there
is a substantial change in air composition. Air pollution causes respiratory
diseases like asthma, bronchitis, lung cancer etc. Air pollution can be
minimised by using L.P.G in place of fuel, wood or cow dung cakes. many
vehicles are now using compressed natural gas which does not produce smoke.
