@mortein: we already saw the almost strongest man in one piece though, and he was about island level.. albeit he wasn't in good health. That goes for the two admirals, and they are near top tiers.. we knew so6p created the moon hundreds of chapters ago.
I think that EOS characters will be much stronger than current admirals or Yonkous, and even stronger than prime Garp Roger and WB.
GMO is the future. Even if current GMOs happen to be bad for you, and there are very few studies which would imply that, that only means we need to do a better job next time.
One more problem is that currently, when we are modifying organisms we are focusing too much on making them fast growing, more resistant to pesticides and pests and aesthetically pleasing instead of making the food healthier and more tasteful. But that's also changing .
