Okay, so we've spent a long time talking about GETTING to 'murica..
But what happens when everyone IS in america? What then?
Everybody meet up in DC
What is up with you and DC?
California has a very mild climate and a massive agricultural base; once we got set up, starvation would almost be a non-issue. We've got some of the best tech in the world out here as well as plenty of renewable energy.
Drought (or whatever you call it) In california, and the fact that a lot of it is somewhat desert? DC is nice, chill, and hell, we've got closeby farming areas in East Coast, what about Pennsylvania?
There's something around 30 million people in California right now and we're still not out of water. Hell, some places don't even have rationing yet. Even if every Bay12er in the world moved here, drought would not be much of an issue. The deserty bits are mostly in the south; as you go north things get much more pleasant. Plus, no snow unless you live in the mountains!
