People have been saying for centuries, if not longer, that the world would soon be coming to an end, because of this crisis or that crisis. But is hasn't yet. It it probably won't for a very long time. The human race is a species of survivors. One way or another, we will solve the current problems and we will survive. Also, advances in agricultural technology creates more food to feed more people. Overpopulation will not be a problem anytime soon.
