Five percent of eight billions is four hundred millions. From that we have both population density and how much time it would take to get back on the eight billions train again at a certain rate. At low historical rates of half one percent of yearly growth we have 1.005^years * 400*10^6 = 8*10^9 therefore years = log 20 base 1.005 = ln 20 / ln 1.005, years = 600.643. If we still have the same land area then population density is simply five percent of now: from two hundred and eighty four people per square mile to fifteen, that is one hundred and ten people per square kilometer to five. To restore to our civilization's standards we need to concentrate people in small areas towards the previous density for those six hundred years.

This might be better suited to the hist board, idk.

If the world's growth rate is falling, why is the population increasing? Is it mostly because people are living longer?

No, it was the leap in fertilizer technology that created the massive population. You can thank Fritz Haber & Carl Bosch for that. Haber's the same Jew who invented weaponized gases in WW1. That started around 1910-1920 and went from there. Population growth was pretty steady before then.

It seems to be leveling out. 12 billion is certainly sustainable as far as basic living needs are concerned (food, a place to live, clean water). Anyway the environment isn't being destroyed by too many people, it's being destroyed by a small fraction of people with lots of money.

This stopped being a discussion on high a long time ago. Africa is industrializing, and the industrialized world re-stabilizes at a heightened population due to the availability of food, health care, and a position in the economy. Growth continues, but the rate of growth has been decreasing for over 40 years.

Population growth has been slowing down for a while now. Also, a large amount of food goes to waste already, and Africa has made leaps and bounds in terms of industrialization in the last couple of decades, so no one will really be forced to diversify their eating habits. If anything, diversifying food sources is almost more of a luxury at this point, as world hunger is going from being a geopolitical issue to being an issue of the lower class.

You're not thinking though time. The world population made leaps and bounds when modernization happened in health care, and that's no coincidence.
