The number of people in the world is growing fast – every year there are about 70 million more people. So, we've got two questions that need answers: Have we got enough space on our planet for so many people? and How can we make sure they've all got enough food to live?
世界人口正在快速增长——每年大约增加7000万人。因此，我们面临两个需要回答的问题：我们的星球有足够的空间容纳这么多人吗？以及我们如何确保所有人都有足够的食物生存？
Many people eat too much meat – steaks, beef burgers, sausages, etc. That's not good for us and we need big farms to produce all that meat. The farms already use 30% of all the world's land: they create greenhouse gases and use a lot of water and energy. However, we can do something to help.
许多人吃了太多的肉——牛排、牛肉汉堡、香肠等。这对我们不好，而且我们需要大型农场来生产所有这些肉类。这些农场已经占用了全球30%的土地：它们产生温室气体并消耗大量水和能源。然而，我们可以做一些事情来帮助解决这个问题。
We can eat meat only one or two days a week, for example, and eat more vegetables – that's healthy. We can also eat some different types of meat – creepy-crawlies! That's right, grasshoppers, worms, flies and lots of other insects. They're the superfood of the future. They've got a lot of protein. Protein is very important for our health, and it's good for our hair and our skin.
例如，我们可以每周只吃一两天肉，多吃蔬菜——这样很健康。我们也可以吃一些不同类型的"肉"——爬虫！没错，蚱蜢、蠕虫、苍蝇和许多其他昆虫。它们是未来的超级食物。它们含有大量蛋白质。蛋白质对我们的健康非常重要，而且对我们的头发和皮肤有好处。
Protein keeps our muscles and bones in good condition, too. There are two more reasons why insects are good food options: insect farms don't need so much water and energy. Also, they don't use so much space.
蛋白质还能保持我们的肌肉和骨骼处于良好状态。昆虫是良好食物选择的另外两个原因是：昆虫养殖场不需要那么多水和能源。而且，它们不占用那么多空间。
For some people in countries in Asia and Latin America, eating insects is not unusual. But for people in Europe and many other countries, it seems very strange.
对于亚洲和拉丁美洲国家的一些人来说，吃昆虫并不罕见。但对于欧洲和许多其他国家的人来说，这似乎非常奇怪。
What about you? Do you eat any healthy food? How much meat do you eat in a week? Perhaps you think you don't eat insects? But maybe you're wrong! Why's that? Because the red food colouring that is in many things that we eat comes from … an insect called the 'cochineal beetle'!
那么你呢？你吃健康食品吗？你一周吃多少肉？也许你认为自己不吃昆虫？但你可能错了！为什么这么说？因为我们在许多食物中使用的红色食用色素来自……一种叫做"胭脂虫"的昆虫！
