Well, I wouldn’t go so far as to say that we could all live “comfortably” in an area the size of Alaska. I for one am glad that we are all spread out and have nothing against urban sprawl or whatever the latest thing the Planners are against. My degrees are in Geography (old school), so much of the baloney we are hearing about Global Warming/Climate Change/Population explosions, etc. were taught in much less hysterical terms 40 years ago.
I wouldn’t want to have everybody live in AK meself, I use that to help put things in perspective for all those who think that we’re killing the earth with overpopulation
