  •  micronutrients too (6+ / 0-)
    Plant growth experiments have shown that concentrations of both nitrogen and the protein Rubisco, which regulates carbon dioxide fixation, decrease under higher CO2 conditions, making many plant tissues less nutritious.
    A couple of years ago, I wrote a long and relatively boring diary about the effect of CO2 on plants. The short version is that grains have less protein and most everything has less micronutrients. In the years since I wrote the diary, I have had blood tests for other reasons that show shortages of everything from magnesium, zinc, and selenium to most of the B vitamins and vitamin D. The last can be put down to living in a cloudy country, but considering I spend most of my money on food, and a carefully balanced diet at that, it's rather disturbing. The wealthy might have access to vegetables that the poor will not, but unless bioengineers becomes a lot more intelligent than they are now, those grains and veggies will not be as nutritious as they are, even now.
