This is one of the ideas proposed by science and academic experts to deal with the problem of feeding the world when the population has boomed to nine billion. This number of humans is predicted to be reached by 2050. The simple answer to overpopulation that nobody is talking about is population control. Do we need nine billion people? Do we have the technology to keep population levels manageable? Yes and yes.
