Many factors cause people to migrate in search for work and pure existence. Climate change, famine, pollution, repetitive natural disasters, political unrests and so on. Indian subcontinent nests millions of entire families migrating internally. Seasonally or permanently, these people relocate for thousands of kilometres, looking for work and having their numerous family do the hardest work for a meagre pay of one person. Contrary to the terms commonly associated with migrants, there are whole communities living to work and working to live wherever the opportunity may arise.
