The causes of air pollution seem to stem from Every citizen who drives a car that is not properly serviced and that does not have emission control devices is contributing noxious gases into the atmosphere.Large industries that do not have filtration mechanisms on their smoke stacks are also contributors. Every government which does not pass or passes but does not enforce strict air pollution legislation is also destroying the atmosphere. One may wonder why these three aspects of society show such a lack of concern with the air they breathe. Well, the underlying cause which motivates all three groups is money. Legislation and enforcement of laws and installation and maintenance of filtration systems cost money. The majority of these three groups seems content to save a bit of money now and sacrifice an invaluable commodity later.
