Dirty surroundings and wastage of paper. others can tell them to stop such stuffs. instead of putting banners or handbills everywhere they could put a big boards so that everyone can see instead of putting small papers everywhere. ppl would just ignore it because its just a small paper that is being wasted . the authorities can ban all these stuffs and instead they can build up huge banners ,so the surroundings look neat as well as there is no wastage of papers . HOPE THIS HELPZZZ U!
