> there is an entire landmass on earth that could be made for us to colonize instead.  true  > we have the technology to do it, why dont we? we don't. the weather is too cold and the further south you go the more we lose planetary electromagnetic fields (can't live without planetary electrical fields).    > we can still build cities in antarctica no , and why ? we have massive warm landmass to colonize yet . entire sahara can be made into a forest, for instance, a lot easier to do.
