The root cause of slavery is lack of economic opportunity and that is compounded by social failures. "We hear a lot about what is pulling peoples into Trafficking situations; It's almost always in international setting, a lack of economic opportunity."
Trafficking in persons is considered one of the gravest crimes in Nepal. In ancient time in Nepal human trafficking was in the form of kamara kamari, Das Dasi and human being were like a commodity they were sold and purchased. But in recent years Nepali men, women and children are also subjected to forced labor, sex trafficking and human organ trafficking. Nepali migrants are smuggled to developed countries. Human trafficking of women is growing to South Asian, Middle East and African countries also besides India.
