That's why you need a feedback mechanism that adjusts the birth rate to match the current death rate. If you set the birth rate in stone age times to match the modern death rate, humans would have died out in stone age times when the death rate was higher. Note that the current birth rate is artificially low due to the widespread use of contraceptives. In fact, the middle class in modern Japan, Europe, and the US have an average birth rate that is slightly below replacement level. | |

" What is this? What would happen if we had some way right now to cut the natural birth rate to match the current death rate? | |
