Overpopulation: You get to cast the deciding vote.

[Clueless Morgan]

  2) Force people to not reproduce as much as they wish (i.e., people who reproduce will be forcibly made sterile).

You've already stated that every other method of trying to bring population levels under control have failed, why would you think threatening people with sterilization if they reproduce would be the magic bullet solution to bringing population levels under control? Without some sort of idea in mind of when the sterilization program would be lifted (a sustainable population size), and measures in place to make sure those measures are implemented when that number is reached (as presumably it would take at least many, many decades if not more than a century or two), I see bad things happening as a result of this.

Since it's obvious you are looking for the pragmatic solution to ensure our survival in the long run, why not simply execute half of the population, specifically old people and others that we don't need in society? I mean, it's cheaper than the technology, funds and investment necessary to control who reproduces and it's not like we are concerned about morality, right?

Kinda makes sense if you're talking pure pragmatics and not the moral question of killing versus sterilizing versus starvation. If all you're after is a lower population, then the thing to do would be to immediately kill half the population -or whatever percentage would be required to bring the population under control. Demands on resources would immediate drop, there would be, probably, and over abundance of food at that point, and you wouldn't have to wait for people to die of natural causes which could take years to happen, and in the meantime they continue to consume resources.

Of course, that would be insanely immoral, IMO... (unless, by some freak occurrence, you get a whole spat of volunteers for the slaughter... )

I suppose my bottom line would be that if I were the deciding vote, I don't know that I could vote to remove a person's right to physical autonomy (that's a big deal to me personally) so I'd have to vote to NOT enforce mass sterilization.

Sorry if this is a repeat of previous sentiments, I didn't read all the posts...
