"We are coming to a point in our history in which we need to start looking for more space" -- Han Admiraal, who thinks we should go subterranean and start building underground.
I've traveled extensively in the central and western United States. You know what I saw? A lot of empty space. There is tons of space for people to live in, grow food in, work in. It just isn't located within 100 miles of a seaboard. Let's spread out into smaller, more sustainable communities.
The city where I live didn't even exist 100 years ago, it was just a dusty stop on a road to somewhere else. Now it's a home to millions - in a desert. Drive 30 minutes out of town and you're in the middle of nothing. What's stopping us from starting new cities in all of this open space? I have to imagine it would be cheaper than trying to excavate a subterranean city under existing population centers.
