In a finite world this means that the per capita share of the world's goods must steadily decrease. Is ours a finite world? A fair defense can be put forward for the view that the world is infinite; or The population problem has no technical solution; that we do not know that it is not. But, it requires a fundamental extension in morality. in terms of the practical problems that we must face in the next few generations with the foreseeable technology, it Garrett Hardin is clear that we will greatly increase human misery if we do not, during the immediate future, assume that the world available to the terrestrial human popAt the end of a thoughtful article on sional judgment. . . ."
