<< So tell me, Nef, what makes the Chinese breed like rabbits, but Americans and Europeans don't? >>
well before any modern science(before 1600 A.D.), the general public didnt know anything about the effects of over-popluation. at that time, China already has a large base of population. Let me remind you, China is one of the most succesful civilizations throughout world history, and it shows in its population (Back then when you can feed all of your population without letting them die of hunger, you are considered prosperous)
so everybody knows about the population function, it is an exponential function. With a large base to start out with, you get a very big number in relatively short amount of time. and that is why China is now over-populated, over-population started in the industrial age. and it wasnt considered a big problem til now. that is why a population control policy is only implemented a relatively short while ago in China.
