Along with major reductions in the energy sector, we need to fundamentally change the way we grow and raise food. If land use, transportation, methane emissions, carbon released from soil, and fertilizer use are all factored in, between 40 and 57% of GHG emissions are related to the agricultural sector (which also uses 85% of fresh water). By moving towards more local, lower meat, and agroecological approaches to farming, these emissions could be greatly reduced. In fact, soil is the largest land-based carbon sink, but industrial farming methods have turned soil into a net carbon emitter. Using methods that increase organic matter in soil could go a long way to reducing CO2 in the atmosphere.
