I was recently thinking about this. Farming is essentially constant repeated removal of extreme amounts of biomass from a land area. We rely heavily on fertilizers for industrial farming.
What is the ultimate source of most of the nutrients that are used to produce the fertilizers? There are massive amounts of carbon, phosphorous, nitrogen, and potassium required.
