Gonna need a source for that claim on higher inputs for human food.
If economics is your excuse for raising animal feed instead of human food then it’s just another knock on capitalism. (Although if you calculated the economic cost of raising/slaughtering/shipping all that meat, I’d wager it’s not cheaper than growing plants for humans to eat)
Also, we farmed animals in the past because they are a good storage for calories when it’s winter and you can’t grow food. We live in a global society now. It’s not necessary. Animals are grown and killed because their meat is pleasurable to eat; simple as that.
