Wouldn't repopulation require sexual slavery of (young and fit) women?
You know, the Kubrick movie Dr. Strangelove showed very well the mentality of people in power when delving into:
- how to repopulate after a world catastrophe
- whom to save to go about it
And their conclusions weren't particularly kind:
- An OVERWHELMING majority of survivors would need to be female to ensure repopulation (plenty of incubator work ahead to repopulate)
- These females would need to be: young, fit, and especially pretty to "motivate" the remaining males whom would need to "perform" to be able to constantly impregnate a ratio of about 10 females to each male (each woman would be expected to birth kids more than once).
- Whom the males would be was not discussed (for obvious reasons to not rules themselves out of the list of survivors), but they would also need to be young and fit (plenty of backbreaking hard labour ahead to rebuild and sperm to generate).
And you can imagine how girls protesting about becoming human incubators would be dealt with...
