And/or live in what is currently empty sky, as urban cores build upward.
There are developments in urban agriculture, too; the main currently
limiting factor is pure economics. If you have the distribution setup to
make it profitable, and suitable building space, you can just buy farming
units and start making money. It is not inconceivable that some future
skyscrapers will be primarily agricultural in this fashion - perhaps tall
enough to reach most clouds and harvesting water from them (so as to not
have to spend their own energy pumping water up).
And there is the potential for lunar-made solar power satellites,
eventually delivering power for lower cost than all current alternatives -
and "outpriced by alternatives" has been the most effective means to shut
down power plants so far, if one wished to e.g. completely dismantle the
fossil fuel power plant industry worldwide, eliminating their impact on our
Sourcing minerals from the Moon and asteroids would significantly lower
mining environmental impacts on Earth, too. It would not be a complete
panacea, but it would certainly help lower the impact of additional
population. Perhaps extraterrestrial mining, vertical/indoor farming, and
solar power satellites supporting 100 billion people on Earth might have a
lower impact than we do today...and I think everyone on this list can
agree, given current slowing trends in population growth, having a lower
impact through 100 billion people would buy quite some time for us to deal
with other problems.
