近年来，发达国家正面临愈演愈烈的食品浪费现象。生活在这类国家的大家扔掉很多的食物，与其对比，另有一些国家的大家面临食物紧缺，饥饿难耐。
How much food do you buy each week? Are you someone who stuffs your fridge and cupboards full of edible1 treats so that youll always have something to munch2 on and so that youll never go hungry? Or maybe, like me, youre more efficient with your shopping, only buying what you need and using up your leftovers3 so that you keep food waste to a minimum.
Throwing away unwanted food has become a big issue in the developed world. While some of us chuck away unwanted items, people in other parts of world face food shortages and are starving. Its a shocking fact that a third of the worlds food is wasted each year. The actual figure is 1.3 billion tons of food, which is enough to feed a billion hungry people.
You may think supermarkets are the main contributors to this mountain of food. After all, they do discard stuff thats past its sell-by-date and they often refuse to sell vegetables or fruit that are the wrong shape or look damaged. Theyve also been criticised for encouraging customers to buy more than they need through promotions4 such as buy one get one free.
But the biggest culprit for creating food waste is us. In Europe an incredible 53% of food waste comes from households, which results in 88 million tonnes of food waste a year. So instead of filling our bellies5, our food is filling up landfill sites its buried and left to rot. Unfortunately this causes greenhouse gases which eventually leads to global warming and climate change.
In Denmark, a woman called Selina Juul has been working hard to tackle this problem. She moved from Russia many years ago and was amazed to see the abundance of food available in the supermarkets. But despite so much availability, she found that people were buying more than they needed and throwing too much away.
She convinced some supermarkets to sTOP selling their items in bulk so that people bought only what they needed. She produced a leftovers cookbook and shes now set up an education programme in schools. This has helped create a significant 25% reduction in food waste, which shows that something can be done.
Clearly, we need to think twice when we put something in our shopping trolley6, and when were at home we should make the most of the food we have using recipes that use up our leftovers or even sharing our excess food with our friends and neighbours.
