    Eating crops directly rather than feeding cows is far more effective than changing fertilizer source.

    cows eat a lot of grass, and usually from land that isn’t suitable for crops. the silage they get is mostly parts of plants that people can’t or won’t eat.

      Paltering.

      Corn and soy grown for the purpose of large animal feed exceeds the amount of cropland used directly for human consumption in areas where <20% of calories and protein come from red meat.

        almost all soy (about 85%) is crushed for oil for human use. the vast majority of what’s fed to animals is the industrial waste from that process.

        only 7% is fed directly to animals.

        i don’t know the numbers for corn, but i do know that globally, about 2/3 of all crop calories go to people.
