In India they are known as bonded laborers, bound to those who gave them or their forefathers an advance or a loan. Human rights advocates call them modern-day slaves. The reports from CNN's Sara Sidner on bonded labor - which can include young children - has spurred hundreds of readers and viewers to ask how they can help.
As one reader commented on the post: "This breaks my heart so much. ... I am not rich, my parents are not but we have never in our entire life experienced slavery. What can I do to help?" Another e-mailed CNN asking how to help: "I would like to help one of the families mentioned in your story from Uttar Pradesh, India. ... how may I best help these families?"
An organization working in India to combat bonded labor is Free the Slaves. Find out more from their site about freeing a village, how it works and how you can get involved.
