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.
The US could feed its own population multiple times over if we used something like 30% of our current agricultural farmland subject to growing animal feed instead for growing things like corn, soybean, and wheat, as well as vegetables and fruit.
We’d still need to import some stuff, but we could cover the vast majority of Americans’ nutrition doing this WHILE at the same time re-wilding the country and helping restore biodiversity.
Hope to see this shift in my lifetime
