Cutting food waste by a quarter would mean enough for everyone, says UN.
With the global population rising, wastage of products including 45 percent of all fruit and vegetables and 20 percent of meat is one of the greatest challenges to achieving food security.
If the amount of food wasted around the world were reduced by just 25 percent there would be enough food to feed everyone on the planet, according to the UN.
Each year 1.3 billion tonnes of food, about a third of all that is produced, is wasted.
Meanwhile, 795 million people suffer from severe hunger and malnutrition. Well-publicised attempts to combat the loss of food – such as recent laws in France that require supermarkets to distribute unsold food to charities – have highlighted the issue of food waste, identified by the UN as one of the great challenges to achieving food security.
