all of the above have been banned by religion actual school of thought, let say for example its not banned than the central govt responsibility is to ban it
this is simple case of human trafficking, and the responsibility purely lies on central/provincial govt
the problem is not related to india, Pakistan, bangaldesh, srilnaka and especially nepal also suffer from it but saying indian govt has nothing to do with it and its a issue of religion is shameful, last I check Nepal isn't a Muslim country
