Sri Lanka is an interesting example as their organic fertilizer mandate would (I imagine, being less nutrient dense) fail to provide enough nutrients to support the increased growth of the plants in the new higher-CO2 atmosphere. The synthetic fertilizer ban situation also doesn't seem to indicate that they would be adept at implementing large scale agricultural changes without throwing the whole system into disarray.

Don't forget to factor in the cognitive impairment from higher CO2 as well - even if CO2 magically made the food both more nutrient-dense and with higher growth rate (instead of higher growth rate with lower nutrient-density) the overall health effect on humans would still be presumably a massive net negative due to the cognitive function decline.

I just detailed on how that will happen, no need to use magic. Increased CO2 will be better for plants worldwide (including deserts) and for agriculture, that's maybe the one positive thing I can find about global warming.

What, you and I are typing right now in a comment thread precisely about increased CO2 resulting in lower nutrient density, so no, you haven't detailed how that will happen.

you need to use less land for the same amount of poor calories (rice,corn,wheat,potatoes), and use the remaining land for highly nutritional food
