Help with these numbers, please…

… seem unable to figure this out for myself!

— Land surface of the earth = 150 million square kilometres

— Inhabitants of the earth (for simplicity this outdated number) = 7500 billion people (that is plus nine zeros)

— Does this permit — in theory — each couple 10.000 square meters = 1 hectare to live on, cultivate and eat from…

— Can someone please verify this calculation…!

— — — — — — — — — — — — — — — — — — — — — — —

Now — obviously — grounds may be too steep (mountains), too cold (ice), or too hot (volcanos)… therefore next should be a calculation of inhabitable land from which nutritious food can be drawn… That is — if my calculation holds water — even if only 75 Mio land are inhabitable… 2 couples will have one hectare land available to them… or each couple half a hectare… Is this correct? Another simple calculations renders this result: On one hectare of habitable, fertile land 100 people should live, if mankind — distributed across the land — stopped industrial farming to do their own seeding, caring and harvest, plus hunt and forage…

The question is this: Exists sufficient inhabitable land on planet earth so all — in a future — society can live on and eat from the land.

Age 71… ready to learn… and share…
