The United Nations Food and Agriculture Organization whose slogan is "helping to build a world without hunger," has come out in support of organic farming as part of the answer to the challenges of global warming, hunger and health issues for consumer and farmers. Nadia Scialabba, an FAO official provided an articulate definition for organic agriculture: "A holistic production management system that avoids the use of synthetic fertilizers and pesticides, and genetically modified organisms, minimizes pollution of air, soil and water, and optimizes the health and productivity of plants, animals and people."
