This is becoming a major problem now in Europe. This practice is adopted by most Islamic nations who contribute largely to this major problem - many African nations are now Islamic yet still before converting to Islam the daughters have been sold off. It would be more cost effective to offer free education to every girl rather than marry her off to an old man who will abuse and force himself onto a young girl, who due to her age will become pregnant immediately later dying in childbirth. Society is then left with too many children and old men who are of little use rather they are a burden to the working population. This has to be put into International statute and consequences of practicing child marriage must be penal.
