If the Earths environment gets real bad due to global warming, it will not
be the end of human life. Nature itself will be destroyed, but humans and
selected animals may continue in a controlled indoor environment. Like
living on another planet like Mars or Eaarth.

nature itself will be fine. individual
species might go extinct, but it is likely
that many others will continue along just
unperturbed. others will thrive in the
new ecological niches created.

i would have enjoyed living on the moon
and having to learn how to grow things in
a closed system smaller than the earth.
with the system i've got going for worms
it would be fun to take it up a notch.

so far efforts at large scale closed
systems have not been very successful so
i think it wise to keep the research
going.

are you aware of any other long term
closed systems like the biospheres? i'm
not. last i looked all similar systems
still need a large source of raw materials
and have to have a large space to disperse
waste products. that alone warns us of
the perils of overpopulation and we are
bound and determined to ignore it...
