Want a glimpse of what it (apocalyptic) might be like if Governments get too big, and socialism/communism takes over? Just watch the epic movie, Doctor Zhivago.
Seriously, only me on procreating?? What have we become? Are we so selfish that the atavic instinct of preservation is gone from us? What do you do when you're left 100k in the whole world, stone age scenario. What's that OTHER? I'm really curious. And especially: how do you intend to preserve the knowledge of mankind if you don't procreate? And...are you plan to eat all day long? There's not gonna be a couch and football or baseball on tv you know?
Food would definitely be a major priority BUT I voted "other" as weapons would be, to me, the first and foremost priority of all. You would have food in the house so that would tie you over till you could search for more and eventually grow your own. BUT weapons are needed for self preservation, bitches. No weapon... no future.
