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.
