Rising CO2 levels are making your food less nutritious

Rising carbon dioxide levels are causing climate change. But they could also be making the food on your plate less nutritious.

This looks great, but as the world
warms it is becoming less nutritious.

Loladze: “Every time you eat, say, a carrot or a bread or potatoes, the quality of it is different than, all else being equal, it was, say, a hundred years ago.”

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.
