The UN agency for children UNICEF is warning that the world is facing one of the greatest food and nutrition crises of our time. That as 45 million children around the world suffer from wasting, 150 million children have stunted growth, and every single year maternal malnutrition contributes to 800,000 newborn deaths. Those figures are released as the Nutrition for Growth summit, which is held every four years, is taking place here in Paris. The summit is designed to discuss the major issues and for global leaders to deliver bold political and financial commitments to accelerate progress on nutrition. In Perspective, we spoke to UNICEF’s Executive Director Catherine Russell. "If you invest in children, it's something that pays off forever down the road," she told us.
