Yes. If the argument is about energy efficiency, I agree. Any system that is less than 100% efficient at turning calories into calories will result in, well, fewer calories.

However, we shouldn't assume health and diet are simply a matter of calories as input. Even conceding that beef isn't a particularly good choice for human health given it's saturated fat content, I don't know that replacing beef in the diet with corn would necessarily result in better health outcomes.

You don't need to 1:1 plant corn for human consumption on that farmland due to increased efficiency.

Options range from other crops, parks, leaving it fallow, solar, growing bio fuels, etc.

Realistically we aren't going to replace beef any time soon, but who knows what happens in the future.

I was referring to 1:1 calorie replacement, not land use.

Ahh ok, but even then I doubt we would stick with corn.
