The problem is the future is hard to predict. The mere fact that birth rates in developed nations are falling below sustainment level calls into question any sort of extrapolation of when or if overpopulation will happen. That's not to say the Earth can support an infinite number of people because it can't; but that doesn't imply any specific trends we see right now will continue into the future.
