I think we may be getting WAY too granular in the things we're worrying about.<br/><br/>There's a billion things you aren't considering once you open up the doors to worrying about specific oxygen amounts or certain amounts of food, stuff that we can't really deal with in a setting like this. It is my understanding that the ships have the basic of everything they need covered and the other ships or things we're talking about are extras.<br/><br/>Otherwise since nobody bought a sewage ship, we're literally shit out of luck.<br/><br/>Anyways, I think this is just getting way too detailed.
