Mumbai ! worst place to live.....

Yesterday I visited Mumbai , economical capital of India and one of the largest city in the world.But after visiting Mumbai I feel bad that this international city is such a worst to live and stay,because it is so dirty where you will see slums,garbage and spitting on all over road and footpath.Situation was very worst at Mumbai central as it is one of important Bus stop but it was such dirty my God you will omitt on the spot if you are clean surrounding loving person.We called this city as international but I do not see any international sign or feature in Mumbai.Our government must have to do something reagrding this because smaller city than Mumbai are much beautiful like Nashik.Nashik has very good bus stop nice railway station , nice greenary and rightly plan city!So really someone has to take serious action over this problem!Then only people can say Mumbai is international city.
