I think by the time Earth is seriously threatened (and I mean the planet itself, not the ecosystem) by the Sun going supernova or some such, the "human race" will be a really outdated concept for the creatures with the blue tentacles and 12 eyes that will be dominant species by then.
Right and wrong I think.
But instead of tentacles, it is most likely that prevailing species would be either bugs (which make already 95% of earth's species overall, and about 20% of earths whole biomass, plus - are tough as hell)...
OR some kind of viruses.
It's not nukes and ozone layer that threats extinction of mankind, but rather diseases. What if AIDS or cancer spreaded airborne? Would be pretty quick demise for us. And new diseases happen quite often, much quicker than cure for them.
Space elevator would not help us here.
