Once I  had an opportunity to read an article which described how a few developed nations secretly disposed their wastes by tucking them away deep into the seas, and how it created an imbalance in the ecosystem, and how it affected the marine life.  So many tortoise and big fishes were found to be dead on the shores next year. It prompted me to visit a suburban area of Patna ,my very own city where the administration had been dumping all sorts of waste materials to create a base for an elevated road to be constructed thereafter. I was amazed  to find that they had been dumping the waste for the last three years as if they were creating a bridge of wastes.
The people around had been made to face and tolerate the stink and the infection of the heap of the garbage. The original idea was to compress the wastes, put soil over it, compress it again and build an elevated road. But, the whole idea was reduced to simply dumping the waste there, not caring about its ill-effects.
The stench was so nauseating but, a long exposure to the same stench had made the people ignorant to the very existence of the discarded materials, as if it was the most natural thing.
I was not at all surprised o see that it was only me who had a handkerchief to her nose. The local people were moving around feeling nothing. This was a classic example of subjecting the local population to such low level of hygiene condition that they don't even realize in what peril they are.
We already have rules for utilizing waste materials but, we have no effective mechanism  to implement the rules.
