So what? Famine has been a thing long before and long after the birth of any modern day ideology. (I say “modern day” because I’m not sure if the very first hunter-gatherers had ideologies.) Even if famine was never a thing, increasing crop yields is still worthwhile research that directly benefits mankind, and it goes beyond boundaries.
A scientist who devoted their entire life to ending hunger just passed away and all you can do is post some generic ideological bait. Somewhere along your ideological quest a line of basic human decency is crossed.
