I am pretty sure that growing rice requires land, water, and transport. And I do not think cows eat human food nor humans would be very pleased to eat what cows eat.

What cows eat? Ah you mean soy. Nah we can’t use that. Would be a shame if the cow used 10x the amount of calories to grow before we eat it when we could eat the crops instead and make your comment look uninformed

How could I truthfully mean soy by "what cows eat", when around here, soy only makes up 1-2% of cattle feed.

You're cutting all the corners available by adding up the fact that you've heard soy being fed to cattle to them only eating soy.
