“Anthropogenic CO 2 emissions threaten the adequacy of protein intake worldwide,” the authors wrote in their paper for Environmental Health Perspectives. The researchers therefore wanted to estimate, for the first time, the global and country-specific risks of protein deficiency attributable to human activities. In India, an additional 53.4 million people may be at risk from protein deficiency, plus another 24.6 million in sub-Saharan Africa. Could the impact intensify in some regions, like Europe, if people shift towards more plant-based diets? The protein content can dive dramatically in C3 crops – like wheat, rice and barley – when CO2 levels rise.
