That is a horse of a different color. Hard to imagine =/= impossible.Originally posted by Psion:
I really can't see how you can have 80 billion people living on a rockball with no atmosphere either.

True. But I remain to be convinced that it is possible. If someone crunches numbers and tells me how much food needs to be imported, how closely packed the population is, what the hell to do with the biological waste coming from 80 billion people on a world that's smaller than Luna, what's so attractive about an airless rockball that 80 billion people would want to live there, how a society would be so totally irresponsible about population growth... then I may be convinced.
Heck, if if everyone breathed out at once, you're dealing with between 200,000,000 and 400,000,000 cubic metres of CO2 exhalation to process right there!
it's not just a question of how much food you need though. Like I said, it's what you do with the waste, what the standards of living are like, the infrastructure you'd need to support that, etc.Was it upthread or elsewhere somebody pointed out that there was a study estimating that, given far less meat consumption, Earth could support 130 billion?
Which begs the question - why allow the population to get so large in the first place?In fact, I think you have just given me an explanation on why the Galian Federation isn't so implausible. On Earth it amazes me the rate at which we are expanding. We need some biomass to support us, and we are encroaching on our environment with our living space. Perhaps they NEEDED to move people offworld to feed them. Perhaps the habitable planets are basically giant farms.
