Climate change effects will go way beyond receding coasts and shrinking farm  regions to to include the quality of air that plants need to produce nutritious foods. When carbon levels in the air increase, the nutrition from foods will decline by up to 30%, severely impacting human health.  Dr. Kristie Ebi  is the Founding Director of CHanGe, the Center for Health and The Global Environment at the University of Washington. She works to highlight the role of health and wellbeing in climate action and to facilitate climate resilience in the health sector.  So far the public worries about \"carbon\" have been it\'s effect on creating a green house around the earth but the increased levels of carbon in the air that we and our crops breathe matters too. Our table talk leads us to understand that \"feeding the world\" is much more than just sufficient calories when nutrient content is depleted. http://fgobalchange.uw.edu
