Their children cannot go to school because they have not enough money to send their children to there. Why you think so many people still suffer from poverty now? The answer lies on the population explosion. A president of a developing country once said, “It is us who are to blame for the poverty because we used to ‘produce’ child without limit.” Although this few words sound simple enough, they have clear pointed out one of the causes of the population explosion.
