The main problem I have with some of the carbon sequestering methods like dumping waste biomass at the bottom of the sea is that that biomass is a mixture of carbon we want to sequester, and nutrients that we really want to put back into the land. Constantly removing biomass from a land area is a really effective method of turning that land into a totally useless area that doesn't grow anything any more.
- mixedmath 7y agoI 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.
