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.
Imagine how much more forest we could preserve if we were fully free (or even, like days of old, fully encouraged, even insisted, and even demanded) to grow hemp. In many ways multiple times more efficient than trees.
