> This will never happen . [...] Better to worry about how to adapt. In ecology, there's talk of population boom/bust cycles that result from biome variation, like a predator going away. This results in more members of a given species than can be supported by the rest of the biome. Then comes the bust. In human terms, adapting is probably mostly about hoping the right warlord owns you.
