The poorest will be most affected by CO2 greening.
Empirical evidence shows that increasing levels of CO2 result in lower concentrations of many minerals in plants tissues. Doubling CO2 levels results in an 8% decline, on average, in the concentration of minerals.

"Declines in magnesium, calcium, potassium, iron, zinc and other minerals in crops can worsen the quality of human nutrition. Researchers report that the CO2 levels expected in the second half of this century will likely reduce the levels of zinc, iron, and protein in wheat, rice, peas, and soybeans. Some two billion people live in countries where citizens receive more than 60 percent of their zinc or iron from these types of crops. Deficiencies of these nutrients already cause an estimated loss of 63 million life-years annually."
