Botanical Nutrition

A new study published in the journal Nature this week titled “Increasing CO₂ threatens human nutrition” indicates that increasing levels of CO2 (such as those predicted to be reached by about mid-century) will result in decreased levels of nutrients Zinc and Iron in crops.

Delhi Daily News, reporting on the new research, commented “An estimated 2 billion people tend to suffer from iron and zinc deficiencies, resulting in 63 million deaths yearly from malnourishment. The reduction in the concentration of these nutrients actually poses a severe threat to mankind related with global warming. ”
