Research indicates that increasing concentrations of carbon dioxide in the atmosphere could decrease some nutrients in crops.
Dr. Samuel Myers, a research scientist in the Environmental Health Department of the Harvard University School of Public Health has shown that some important crops raised in CO2-enriched experimental fields have lowered levels of zinc, iron and protein. Grains like rice, wheat and soybeans were grown at CO2 levels expected around 2050, and researchers saw decreases in these nutrients from 4 to 10 per cent. For populations where iron and zinc deficiencies are already a problem, the lowered levels of these nutrients could be a significant problem in the the future.
