Minor girls should not marry. At the age of 15/16, a human may not get much ideas about life. They may not select right life partner . They may not have much knowledge abt married life.
They may or may not get any problems physically. But see their age. Its just 15/16. How much they can handle the house?
If they get children in 16th,18th age...
1. Will they complete their studies? 2. Their life starts running here and there. Taking care of children. Can they really take care of children ? 3. Some times they see the same age girls having no responsibilites. And may scold their life.
This all affects on their CHILDREN/ Next Generation.
I think instead of 18, it should be made as 20. So that girls also can select right life partner.
