Food losses: what are we talking about?
For non-human uses Non-edible Harvest losses Postharvest losses Process losses Distribution losses Consumer waste

Loss of economic value: 750 billion US $ (FAO, EIU)
Why are food losses an issue?
Loss of nutritional value - kcal lost or wasted: 63% for roots and tubers, 42% for fruits & vegetables (WRI)
Environmental impact on climate and availability of resources (energy, water, land, nutrients)
●64 litres of water for 1kg of tomato Food security impact: even if just one-fourth of the food
currently lost or wasted globally could be saved, it would be enough to feed 870 million hungry people in the world (FAO)
Food losses and waste go against ethical/moral values
