A fair defense can be put
forward for the view that the world
is infinite; or that we do not know
that it is not. But, in terms of the
practical problems that we must
face in the next few generations
with the foreseeable technology, it
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 population is finite. “Space”
is no escape
