Why should I have to state the obvious? Factory farms are terrible for the environment both in the short-term immediate vicinity, and in the long-term globally. They are massively increasing our exposure to antibiotic resistant strains of bacteria. They expose workers to serious health risks. They treat their animals inhumanely. If you are not troubled by at least a subset of those things, you are either irrational, or your base values are so profoundly opposed to my own that I consider you an obstruction.
