It is definitely true that by lowering the amount of food waste (like food retail companies letting their employees bring almost expired food home to consume etc etc). I just unfortunately assume that we won’t really improve in this food waste area.

Eugenics and genocide in the name of overpopulation could theoretically go into power (or comeback with eugenics), although I think the chance of that happening will be low, atleast in countries like Europe and north american countries, but your point is understandable.
