Notes on the menace of heap of garbage
Answers
We do dream of being a developed world by 2020 or earlier, but actually at least to this date, our country, as far as its major parts are concerned, is only a big slum. Wherever we go, we see heaps of garbage lying in the open.
These heaps are not cleared for months together as the municipal van shows up only occasionally, say after a week or so. The situation is very serious. The problem becomes acute if a marriage palace is near a locality. It is a common sight that all the waste from marriage palaces is dumped indiscriminately and without impunity on roadsides and at open places.
Sometimes, the scavengers strew the garbage quite indifferently all over the locality and to the great chagrin of the residents of the area; crows collect bones from the garbage and throw them on the roofs of houses.
Polythene and other light material are also usually seen Uttered all over the particular place of garbage and around it which gives the locality a very shabby look as well as it creates a suffocating atmosphere with its most rancid and raucous stench.
This garbage is cleared only and if at all, a VIP visits the locality, otherwise, mosquitoes and flies are the only ones who thank the authorities that are for such a state of affairs.
