A report 1 that at least a third of the 4 billion tonnes of food the world produces each year never gets as far as our mouths. Between 30% and 50% of food 2 in Europe and the US is thrown away. Britain—and much of the rich world—has got used to filling the fridge with what looks nice, not what it 3 needs. The cost of that indulgence is ￡10bn annually. Globally, the cost, in money, energy and ever-scarcer water, is 4. Our future food security has been 5 the top 10 of current global worries. The prospect of feeding a mid-century planet of around 9 billion people looks impossible without major changes to farming and our diet. If you 6 the United Nations Food and Agricultural Organisation's call 7 production to be increased by 70% to feed the population of 2050, most of the work will be achieved just by being a bit more thrifty. All we have to do is to 8 better what is already there. Throwing food out is easy. However, using it sensibly, especially the less attractive bits, is not. The urge to bin and buy again, 9 by multimillion pound advertising campaigns, is all the less resistible now because, despite recent price rises, for most of us, food is cheap. At Christmas, the average family spent just over ￡100 on the big meal, a quarter of 10it spent on presents.
