A study in the journal Nature finds key agricultural crops grown in an elevated carbon dioxide environment can contain less zinc, iron and protein.

In this Living on Earth segment, lead author Sam Myers tells host Steve Curwood that atmospheric CO2 levels are expected to reach 550 parts per million by mid-century, which would be adverse for staple crops that support human nutrition.

Both Sam Myers and Steve Curwood are members of the Center's affiliated faculty.
