Rising CO2 Threat to Nutrient Levels in Crops

Rising levels of carbon dioxide in the atmosphere may cut the nutritional quality of some of the world's most important food crops, warn researchers

Researchers have warned that rising levels of carbon dioxide in the atmosphere may cut the nutritional quality of some of the world's most important food crops.

They say the amounts of two important nutrients, zinc and iron, were found to be lower in wheat, rice, soybeans and field peas grown in open-air fields where the scientists created CO2 concentrations at the level they forecast for Earth by roughly 2050, about 550 parts per million.

"This is important because almost two billion people globally receive most of these two nutrients (zinc and iron) by eating crops," says University of Illinois plant biology professor, Andrew Leakey, one of the researchers.
