Of the total area that is used by humans (Agriculture, Urban and Built-up Land),
- urban and built-up land is 1m km²,
- agriculture is 48m km²,
so agriculture is 48 of 49 millions km² used, that’s 98%. The remaining 2% are all streets and housing and other infrastructure together.


Yeah, and those extra steps require more land and more water and more transportation and more harvesting and more processing etc etc. Every extra step makes the whole system less efficient. We’re essentially sacrificing farmland.
