Im not geneticist, but i grew up on a farm. I always grind my teeth when people talk about miragle plants with high yields.

The plants need to get their energy and nutritions from somewhere. If you just create gmo plant that can absorb nutrition better from soil it also means you need to fertilize that soil that much more and make the crop rotation that much faster, or risk making the fields arid.

But plants that survive larger temperature shifts, more extreme weathers and pest might be necessary for us in the not so far future. Lets just hope in the future those are used for humanitys betterment and not making rich richer.
