A third of food production on this planet done by smallholders, and the easiest way to make sure the other two-thirds doesn't get wasted is to change the distribution system (not with technology). It should not be used to make high-fructose corn syrup in the US. It should not be grown in Arizona to feed cattle in Saudi Arabia. The technology is a sticking plaster over our dumb world, and it is falling off
Then you realize most of our ancestors fled from both of these situations at the first opportunity.
Everything else is either trying to blame "the system" for ideological reasons ("capitalism is bad", "Westerners are bad"), or trying to cope by squeezing quality of life ("don't travel", "don't eat meat", etc).
