You’re right. I made a pretty ridiculous error of laziness writing “directly” when what I ought to have said was more along the lines of indirectly, essentially, etc. As far as I understand it, agriculture at its current scale requires a level of nitrogen input (via ammonia) that can only be supplied by the Haber process, which requires an amount of energy that we have no hope of generating by entirely renewable and sustainable means.

If you mean that there too many people on earth, you are wrong. We just use the resources unwisely. 62% of earths biomass is livestock.

99.9% of earths biomass is either humans, our livestock, or our pets. We are beyond fucked when the collapse starts.
