Whow, wait a sec, I didn't say how hostile it was -- I just said people can't live in those regions. We are not universal. We can only adapt to so much -- but when you take away the appropriate amount of oxygen, or decrease the temperatures enough, we can't survive. We could survive if we had any way to install facilities there, but remember these are diagonal slopes - steep slopes.
(Ihope you know I'm not being harshly serious; most of the arguments, while the facts may be true, are meant as a fun)
