One of the greatest ironies of the modern world is that in some parts people go to bed hungry every day, while in other parts food is being thrown away. The United Nations has now calculated that if the amount of food wasted were reduced by just 25 percent there would be enough food to feed everyone on the planet. An astonishing third of all that is produced is wasted, including about 45 percent of all fruit and vegetables, 35 percent of fish and seafood, 20 percent of dairy products, and 20 percent of meat. Reducing food wastage would ease the burden on resources as the world attempts to meet future demand. The UN has identified food waste as one of the greatest challenges to achieving food security.
