1. 01How Much Water Is Hidden in Our Food?

   Hello, everyone. We usually think about the water we drink or use for showers. But there is also water we never see: the water used to produce our food. Today, I'll show you some surprising numbers.

   大家好。我們通常會想到喝的水，或者洗澡用的水。但還有一種我們從來看不見的水：生產食物所用的水。今天，我要給大家看一些令人驚訝的數字。

2. 02What Is a Water Footprint?

   A water footprint is the total amount of water used to make a product. For meat, it includes the water used to grow animal feed, the water animals drink, and water for cleaning.

   水足跡是指生產一件產品所用的水的總量。對肉類來說，它包括種植動物飼料用的水、動物喝的水，以及清潔用的水。

3. 03The Numbers

   According to the Water Footprint Network, one kilogram of beef needs about fifteen thousand four hundred liters of water on average. Pork needs about six thousand, and chicken about four thousand three hundred.

   根據水足跡網路的資料，1公斤牛肉平均需要大約15,400升水。豬肉大約需要6,000升，雞肉大約需要4,300升。

4. 04Why Beef Needs So Much

   Why is beef so high? Most of the water is used to grow the animals' feed. Cattle live for years and eat a lot before they become food.

   為什麼牛肉的用水量這麼高？大部分的水都用來種植動物的飼料。牛要活好幾年，在成為食物之前要吃很多東西。

5. 05A Picture to Remember

   Here's a picture to help you remember. The Water Footprint Network says the water footprint of two hundred grams of beef is about the same as forty-seven eight-minute showers.

   給大家一個好記的畫面。水足跡網路說，200克牛肉的水足跡，大約相當於洗47次8分鐘的淋浴。

6. 06What We Can Do

   This doesn't mean we all have to stop eating meat. Small changes help, like choosing chicken or beans a few times a week, and not throwing away food, because wasted food means wasted water too.

   這並不意味著我們都必須不吃肉。小小的改變就有幫助，比如每週選幾次雞肉或豆類，還有不浪費食物，因為浪費食物也就是浪費水。

7. 07Conclusion

   To sum up, every meal has hidden water. Knowing the numbers helps us make better choices. Next time you order a burger, remember those forty-seven showers. Thank you.

   總之，每一餐都藏著看不見的水。瞭解這些數字，能幫助我們做出更好的選擇。下次你點漢堡的時候，記得想想那47次淋浴。謝謝大家。
