*Global health and environmental costs of food industry are $10tn a year – UN

*[The food industry's] "price tag" of non-communicable diseases, malnutrition, poverty and harm to planet is 10% of global GDP, says UN food agency.*

These costs are not all the same in kind. It might be possible to entirely avoid the noncommercial diseases caused by harmful diets, as well as malnutrition and poverty, at no cost by improving some aspects of social organization.

However, diseases caused by byproducts of food production, and "harm to planet", are a different kind of matter. We could surely reduce those, but we cannot assume a priori that reducing them to zero is possible.
