Among the many considerations, often recurring in this occasion, I want to add mine too:
Women in the world are badly treated. But then I thought of something more serious: Afghan girls sold by their father to pay their debts by opium traffickers. The story is simple. In the provinces of the South West of the land the farmers are forced, by the failure of all eradication policies, to produce and often also to refine opium. The problem is that (as happened in different historical epochs) the farmer who fails because of unforeseen natural elements to meet commitments end up incurring debt. The fact is that before selling the land, become slaves or settlers to a master, in this land you pay the debt by selling daughters to traffickers. And much smaller are much more worth.
