New places to colonize because we are running out of livable land is not the main issue. In case of an extinction level disaster, most land/ocean based humans may be wiped out. Having a "backup" colony on a different planet is needed in this regard. And we are talking about colonizing another planet, so zero G vision problems would not be that much of an issue I guess.
- prewett 10y agoWhat disaster are you imagining that takes out an underwater colony? It'd be completely sealed off from the water, so you could vaporize the entire ocean (unlikely) and atmosphere and it would still be okay. The only thing I could see affecting an underwater colony would be an earthquake, but I'm having trouble imagining an earthquake big enough to wipe out all surface life.
