Question

Even after prohibition of child marriage act ,child marriages are still going on here and there suggest some measures to stop this Dogma

Answer 1

Child marriages are still practiced in certain parts of India.  Though there is an act condemning child marriage, it is still conveniently ignored. The main reason for such a condition is the ignorance of people practicing it. They are uneducated and lack a basic knowledge to understand the problem and its underlying problems. Support groups must be sent by the government to empower such people with the right knowledge. Not only that, strict laws must be in place to punish those who practice it. An easy to reach call center or an officer must be deployed in each village to reach out in the case of child marriages.

Answer 2

To stop the child marriage girls should be educated and should be taught that they are not allowed to marry at such an early age, with children parents should also be educated that they should not get their children married before a certain age. 
Other than that serious actions should be taken against the people who support the idea of child marriage and they should be penalized for carrying out such acts.
There should be groups of people who are against child marriages, they should get together and should spread a word that it is unlawful for a child to get married, they can make NGO's to support this idea.
