I say we should discover fusion really fast, if we want to avoid an energetical shortage in the next century.
I would not worry about overpopulation ; if there's one thing where mankind is self-regulating, it's population. You know, demographic transition : you go from a really high birth rate, because there's a really high death rate, thus a really slow growth (medieval european countries), to a high birth rate, low death rate transition, resulting in huge growth (India, Maghreb, ...), because scientifical progress has not yet impacted sociological trends, to a low birth rate, low death rate in "developed" countries (EU), where sociological trends have fully absorbed scientifical progress (contraception, child planning, women working, high studies).
But anyway, I'm optimistic. I'm pretty sure we'll find a way to survive.
