Malthus argued a century and a half ago that man, by using up all his available resources, would forever press on the limits of subsistence, thus condemning humanity to an indefinite future of misery and poverty.

The truth or falsity of his prediction will depend now, with the tools we have, on our own actions, now and in the years to come.
