Warming may put 53 Million Indians at protein deficiency risk’

Human-caused carbon dioxide emissions may put 53 million people in India at the risk of protein deficiency by 2050 due to a decline in the nutritional value of rice, wheat, and other staple crops, a study warned on Wednesday (2 August). If carbon dioxide (CO2) levels continue to rise as projected, the populations of 18 countries may lose more than five per cent of their dietary protein by 2050, according to the findings by researchers at Harvard T H Chan School of Public Health in the US. They estimate that an additional 150 million people may be placed at the risk of protein deficiency because of elevated levels of CO2 in the atmosphere. This is the first study to quantify this risk.
