Even so, the Malthusian argument thus far has not resulted in the human starvation catastrophe he envisaged. Instead, the catastrophe has been displaced. We have innovated our way towards sustainable human economies - but at the expense of the environment. We turn the Amazon rain forest into beef pasture, thereby feeding ourselves and killing nature's diversity and the primitive and non-human populations that depend upon it.
This is one of the other main reasons we are in the early stages of an extinction cycle.
We need somewhere like Mars to work for us. If only as an agricultural resource. Or maybe we can create an atmosphere on, and bring sufficient water to, the moon somehow. Or we stop making quite so many babies.
