Rising CO2 and diminishing food nutrients
The atmosphere is literally changing the food we eat, for the worse. And almost nobody is paying attention.
The vitamin, mineral, and protein contents of plant foods have been declining over the last 50-70 years, and research is pointing to rising levels of CO2. Plants use higher levels of CO2 to make more sugar and carbohydrates. The decrease in goldenrod protein may also be a factor in bee colony collapse.
