This article discusses how rising GHGs are causing our food supply to become less nutritious, and that could put more people at risk of malnutrition.
Irakli Loladze, of Nebraska’s Bryan College of Health Sciences, studies how carbon dioxide levels affect plant nutrients. He analyzed studies from around the world that examined the nutrient levels of plants grown in experiments with elevated levels of CO2.
The data include more than 7,000 samples of 130 plant varieties, including rice, wheat, and other grains, as well as fruits and vegetables.
Loladze says the overall trend is clear. “Rising CO2 lowers the concentration of minerals, so calcium, magnesium, zinc, iron, they all drop.”
