I think there is an argument that agriculture is highly inefficient because we can't track externalities well. US topsoil in our bread basket was 14 inches a hundred years ago. It is down to 4 inches now. When it goes, we go.
- onlyrealcuzzo 4y agoI'm under the impression that an acre inch of soil weighs ~170k pounds. So if we're losing .14 inches of topsoil per year - you only need to replace ~23k pounds of topsoil per year. Probably less than half of that needs to be compost. I'm also assuming loss was worse in the past than it is currently. So you'd need even less compost. This sounds bad, but not like something that can't be worked around. And honestly, it sounds like it could be a good thing for there to be huge demand for compost.
