“About half the world does not have a healthy diet. Of the 8 billion people on the planet, roughly 1 billion live in extreme hunger. Another 2 billion live with one or more micronutrient deficiencies, anaemia, vitamin deficiencies or omega-three fatty acid deficiencies, which are absolutely debilitating for health. Another billion people are obese,” said Jeffrey Sachs, Director of the Center for Sustainable Development at Columbia University.
