It is an interesting article -- impossible to refute much of it, and I don't know what to think . But I might add , in the book ' Australia 2050', authored by Australia's Centre for Strategic Analysis , on page 133 in the National security and Intelligence chapter they discuss population and there is a small paragraph that reads ; " However, a natural chain of development will, it seems, in a century or so, reduce the spike in human population numbers. The signs of reduced population growth rates are already evident , and the prospect for what could be termed neo Malthusian adjustments in population levels, and in the quality of human life no longer seem far fetched ". Not sure what to make of that either.
