I don't think that supporting 6.2 billion, let alone, 10 billion people is a reality without technological miracles. And since an age of contraction and decreasing energy such miracles will be less likely to occur I think we are better off preparing for a shrinking population.

Why are so many people so determined to preserve populations? Could it be that die-off may be the one thing that saves our planet for future generations?

But then one gets to the question, would I be so ready to accept this solution if I was the one dieing-off? I'm not so sure if I would. In that case, being white and from America, am I not saying that my life has more value than someone from China, India or Africa?

I would argue that since I had no choice as to where I live and where other's live I am simply advocating the natural remedies to overshoot, and sooner than complete overshoot might perscribe. Can I ever be totally absolved from the fact that my continued life is based on the ending of other's lives? Not at all. But if that fact is held in reverance, and one never advocates for violence to others because "I am better," then I think there is something noble about trying to find a way that works (at least for a lot longer than techno-society). I cannot control what the entire world does, and even if I could, would I want to feed everyone? Probably not, because overshoot (imposed by nature/2nd law of thermodynamics) will become a reality eventually, to one degree or another.
