There are serious challenges to global food supply everywhere we look. Intensive use of fertilisers in the US Midwest is causing nutrients to run off into rivers and streams, degrading the water quality and causing a Connecticut-size dead zonein the Gulf of Mexico. Chocolate production will soon be challenged in West Africa – home to over half of global production. A variety of nutritional impacts are predicted due to increased atmospheric carbon dioxide – including decreased protein content in food, which has a potential to exacerbate malnutrition. And this is just a very small sample of the risks to the food supply chain that are foreseen.
