But the vitamins and minerals come from the soil and there's only so
much of that per acre. Fertilizers can help some, but they are limited.

Much of the genetic engineering and hybridizing increases yield while
leaving nutritional value the same or even worse.

So Crop rotation is simply an empty dream?

No, that's an independent variable. It works--with or without the
yield-increasing methods. So you have one set of factors increasing
yield and proportionally decreasing nutrition, and another factor
partially compensating.

On the other hand, being undernourished and feeling hungry is worse than
being undernourished and not feeling hungry.
