Pollution of garbage increases in cities and towns where there is no proper system of garbage collection. Households have to simply collect the entire garbage of their houses and place it to outside home in dustbin or bag. Its collection is the task of civic agency of the area. If garbage collection agency or contractor does not play its role properly and does not collect the garbage regularly then the problem of this kind of pollution would obviously arise. Improper disposal mechanism is another cause of this type of pollution. If garbage collection agency simply collects the entire garbage of its area of responsibility but does not dispose it off in proper landfill site then it would litter around here and there and most of it would pile up in streets and other areas. It would eventually cause several diseases due to mushrooming growth of harmful bacteria in it.
