They forget that God gave us the brain to think of a solution to our problems. One such solution to overpopulation is birth control.
These people think God will come down from heaven to help them, after He has given us brain to think and wisdom to apply to our best. Many parents aren't considerate at all and they keep giving birth while bringing these children to the world to suffer. I shake my head when I see kids roaming around the street, begging for food.
There is a student in my school, he is always found after school, at a house where he fetches water, go on errands for these university guys just to make little money for himself. It is what he does daily. Now imagine such a child who has been exposed to such a life because of parent's ignorance, and in another way, carelessness.
Seriously, I hope a law could be enacted by the government which should be hold strongly and parents who violate the law should face the consequences.
