Food waste or food loss is food that is discarded or lost uneaten. The causes of food waste or loss are numerous, and occur at the stages of production, processing, retailing and consumption.Global food loss and waste amounts to between one-third and one-half of all food produced. Loss and wastage occurs at all stages of the food supply chain or value chain. In low-income countries, most loss occurs during production, while in developed countries much food – about 100 kilograms (220 lb) per person per year – is wasted at the consumption stage
United Nations: Under the UN's Save Food initiative, the FAO, UNEP and stakeholders have agreed the following definition of food loss and waste: Food loss is the decrease in quantity or quality of food. Food loss in the production and distribution segments of the food supply chain is mainly a function of the food production and supply system or its institutional and legal framework. Food waste (which is a component of food loss) is any removal of food from the food supply chain which is or was at some point fit for human consumption, or which has spoiled or expired, mainly caused by economic behaviour, poor stock management or neglect.
“Please don’t waste food. Live simply, so that others may simply live.”
