Sheela Adivasi holds her 18-month-old son Deepak at a Nutrition Rehabilitation Centre (NRC) in Badarwas block, in the central Indian state of Madhya Pradesh March 7, 2008. A couple of months ago, Adivasi's infant son fell sick and his eyes filled with pus. By the time the infection cleared up, Deepak's pupils had turned a pearly white. He is now permanently blind. It did not help matters that Deepak is malnourished, as are half of all young children in India. His belly is swollen, his dry skin speckled with dark dots, and his hair is thin and yellowing. Had he not been so starved of vitamins, he probably would have suffered only an itchy but harmless bout of pink eye. To match feature INDIA-MALNUTRITION/ REUTERS/Raj Patidar (INDIA)
