In order to replace all of the “inorganic” nitrogen fertilizer that we currently apply in industrial farming and use more “organic” methods – namely using cow manure as fertilizer, we would need an extra 7 billion cattle grazing on an estimated 30 billion acres of pastureland.
Yes, the impacts on land use and climate would be positive if “we” all ate a little less beef, but the land use and climate impacts of moving to 100% organic vegetarianism would be disastrous. That’s just a glimpse of the inconsistency of the organic farming movement – more coming later.
As I’ve asked before, does a plant know the difference between one nitrogen atom and another? Does it know if one came out of the air via natural gas powered factories, or whether one came out of the rear of a cow?
