Sagarika Ghose: The story of Prabhu and Guru Dhodiya and the terrible plight of manual scavengers. They do their job standing all day in human waste, standing in the unbearable extreme stench of night soil; they often have to stay dead drunk to do this job. They are sometimes unable to eat because of the human waste they are surrounded by. Many of them get asthma and the life expectancy is 30 years for many in their community. Our sister channel IBN Lokmat reported on manual scavengers in Pandharpur, Maharashtra leading the Maharashtra government to reinforce a ban. Actor Aamir Khan has also taken up the issue with the PM and on his show Satyamev Jayate. But despite the law, despite the ban, why is manual scavenging continuing.
