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 big takeaway for me is that maybe we should cut down on animal protein and have more plant protein in our diets.
We feed livestock almost as much plant food as we do ourselves (6m2 km vs 8m2 km). Not to mention the space taken up for grazing uses most of our agricultural land.
