I just want to take over Antarctica and legalize weed there... reminds me, I need to work on my next update for that blog...
if it's survival you're concerned about... a self-contained self-sufficient Antarctic colony could probably ride out a nuclear winter or biological plague in ease... and it'd be a hell of a lot easier and cheaper than going into space...
and imho our present civilization hasn't really produced anything truly great worth saving... the majority of our greatest achievements technologically are destructive... mass production creates mass pollution... nuclear power makes nuclear waste... etc...
in the grand scheme of things, nothing lasts forever... all civilizations eventually collapse... at some time sooner or later humans will become extinct... and every trace that we ever existed will fade to nothingness... such is the nature of the universe...
don't worry about it so much... just sit back, roll a blunt and enjoy your life
