True. Corn is often grown on land where it shouldn’t be, contributing to erosion. And it takes more energy to produce than the ethanol it makes if I remember correctly.

It has about 1.5 return of investment in energy. Oil has 11 return of investment alongside a huge wealth of useful byproducts. But corn is sustainable. If we want it to be.

I was under the impression that monocrops have unsustainable implications. I don't know a lot about it, but I thought it was more complicated than that.

It is. And all monocrops are unsustainable. But with the correct mix of rotations and fertilizers (potassium,calcium and other minerals) extensive farming can be sustainable
