> To feed a growing population, it is essential that the global agri-food system be managed to efficiently convert crop production into calories for human consumption.

It's really not. Efficiency is the enemy of redundancy. Countries want food security, so they must therefore produce excess calories.

It’s really, really not. Crop land per capita has been going down for decades despite richer diets, and all the biofuels and livestock feed [1]. Let’s not forget that advanced drugs to stop people from overeating the abundant food are a $60 billion and rapidly growing market.

I think it's important to a point, to be pedantic. But yes, global food production is well over the hurdle of production volume to "feed everyone", even for highly redundant crop yields. The remaining challenge is purely logistical and of course combating unchecked profit motive that's become malignant.
