Anyway, in the last episode I saw they talked about what would happen to Washington DC if all the people were gone... turns out, DC was built on a swamp and without people around to drain the water it likely will become one again. Basically, the Capital Wasteland should be under water... but it isn't. It's gotten drier and the river seems to be receding. I thought about why this could be and could only think of one explanation: Ice Age. You see in an Ice Age the world doesn't just get colder, it actually gets drier as well as more and more of the Earth's water becomes locked up in glaciers. Eventually, the mediteranean sea might become just a huge salt plain.
Or am I just thinking too much about this and should just accept that its only a game?
