BBC Ideas｜如何解决食物浪费问题？

One third of the food produced globally every year goes to waste. Imagine that you go to the supermarket and you get three bags of groceries. One of those bags is going directly to waste. Between our busy lives and sometimes just simply not knowing what to cook, throwing away old food seems inevitable at times, but wasting less food would benefit both the planet and our wallets.
你有没有扔掉过发芽的土豆？这可能看起来不是什么大事，但这正是英国每天丢弃的290万土豆中的一个。全球每年生产的三分之一食物最终都被浪费掉了。想象一下你去超市，买了三袋食品，其中一袋直接被浪费掉了。在我们的忙碌生活中，有时仅仅是不知道要做什么菜，丢弃旧食物似乎在所难免，但减少食物浪费对地球和我们的钱包都有好处。

Food waste has a massive economic impact, with the average household of four people in the UK wasting around £1,000 worth of food each year. It can't be right, in a world of the 21st Century where 800 million people already struggle to get enough food, that a third of the food produced is lost or wasted, and so many people are going hungry. And we can't ignore the impact on the environment. It's been estimated that if food waste were a country, it would be the third largest greenhouse gas emitter after the US and China.
食物浪费对经济有着巨大的影响，英国一个四口之家平均每年浪费的食物价值约1000英镑。在一个21世纪的世界里，8亿人已经难以获得足够的食物，而全球生产的三分之一食物被损失或浪费，许多人还在挨饿，这是不对的。我们不能忽视食物浪费对环境的影响。据估计，如果食物浪费是一个国家，它将是继美国和中国之后的第三大温室气体排放国。

You might think that supermarkets were the main culprits here, throwing away unsold products. But in fact, only around 2% of the food waste in the UK happens in supermarkets. The vast majority, around 60%, is in our homes. Luckily, there are lots of things we can do to reduce food waste at home.
你可能会认为超市是主要的罪魁祸首，丢弃未售出的产品，但实际上，在英国，只有大约2%的食物浪费发生在超市。绝大多数，大约60%，是在我们的家中。幸运的是，我们有很多方法可以减少家中的食物浪费。

By far the most wasted foods in our homes are fresh fruit and veg. Planning meals can really help make sure that you're buying what you need, and you're also thinking about how you can use up leftovers, which can make a great lunch or a meal to put in the freezer for another day.
我们家中最常浪费的食物是新鲜水果和蔬菜。规划餐食真的可以帮助确保你购买所需的食物，并且你也在考虑如何使用剩余的食物，这些剩余的食物可以做成很棒的午餐或者冷冻起来改天再吃。

Understanding what the dates mean on our food packaging can make a big difference to how much food we waste. The ''best before'' dates are the ones that tell you that you can rely on your senses to judge if whatever you are consuming is OK for you. Whereas a ''use by'' date means that food has to be used or frozen by that date. Putting things in the right place can really help you use your food for longer. So storing apples and potatoes in the fridge, for example, you'll get three months longer to use them. The only fruit and veg that don't belong in the fridge are onions, bananas and whole fresh pineapple.
理解食品包装上的日期标识对于减少食物浪费至关重要。最佳食用日期是告诉你可以依靠你的感官来判断你所食用的东西是否适合你。而安全食用日期则意味着食物必须在该日期前食用或冷冻。正确存放食物可以帮助你更长时间地使用它们。例如，将苹果和土豆存放在冰箱里，你可以延长三个月的使用时间。唯一不适合放在冰箱里的水果和蔬菜是洋葱、香蕉和整个新鲜的菠萝。
