Population explosion is a problem that many nations have been facing for a long time. Hence, in order to tackle this problem, they even imposed many rules and regulations like many countries have restricted the number of children the public can have. As a result, these countries will face the problem of having a large portion of older folks than young ones in the coming years. Personally, I think it is a negative development because youth is the future of a nation, and the birth rate is degrading naturally too.
