Yet we hung on and tens of thousands of years later we reached a staggering one billion in number. That's usually pegged at around 1814. Lo and behold, in barely two more centuries we've grown to 8 billion. We've accompanied growth in raw numbers with considerable increases in longevity and per capita consumption.
