>>13138352Some rough numbers here but: the amount of urbanized landmass was roughly 3% in 2003, we've grown in population by around 25% since then, so let's say around 3.75% of land is urbanized
in 2016, the landmass that was used for growing food was 38%. 1/3 of which consisted of cropland and 2/3 which consisted of pastures for raising livestock
I would estimate that number could've gone up but since the amount of hectares of land for food production per capita has been steadily decreasing since 1961 and the trend seems ongoing, I'll just stick with the 38% land to support a population of the current size, but it could go down, idk, maybe 30%? 20%? it depends on how land efficient we become at producing food
so we currently are at:
>3.75% for people>38% for foodassuming at some point we colonize a hundred percent of the land of the earth (god fucking forbid):
we would reach our limit with current efficiency at around
>9% for people>91% for foodthis would be around 18.68 billion humans
i don't really know much about anything related to agriculture, nature, or demography, but 18.68 is a cool number as a rough estimate of the upper limits, right?
I read somewhere that the UN says we'll cap at 12 billion and it'll slowly stabilize into 10 billion indefinitely
what do you guys say?
