This is a case of spreading FUD by presenting true facts in a sensationalist light.
we have been breeding agricultural plants for higher carbon concentrations, at the expense of everything else in the plant, since the dawn of human domestication of plants. This. Is. Not. New. And as such, should not be scary or cause for alarm.
to the extent that global CO2 levels are adding to the normal trend of breeding pants for higher yields, itâ(TM)s is likely to be the least significant way in which global CO2 levels pose a risk to you. Sea level rise, heat stroke, water shortages, resource wars, ecological systems collapsing ⦠all far, FAR more dangerous than a few extra calories per ton of grain. Most western diets are biofortified with minerals and vitamins already, so the plants natural contribution to your diet is already negligible in many situations.
