Thirsty work

The water needed to produce everyday goods and beverages

WATER is a precious commodity, as any farmer in drought-besieged parts of China, America or Kenya knows only too well. Consumers may already be aware of the environmental impact of producing goods in terms of energy or pollution, but they might be surprised to learn how much water is needed to create some daily goods. A cup of coffee, for example, needs a great deal more water than that poured into the pot. According to a new book on the subject, 1,120 litres of water go into producing a single litre of the beverage, once growing the beans, packaging and so on are measured. Only 120 litres go into making the same amount of tea. As many as four litres of water are used to make a litre of the bottled stuff. Household items are even thirstier. Thousands of litres are needed to make shoes, hamburgers and microchips.

 
使人口渴的工作

水是重要的日用品

沒人比中國、美洲、或肯亞被乾旱困擾至極的農夫更清楚的了

消費者可能對於製造活動在能源或污染議題上的衝擊非常清楚

卻會對製造商品所需消耗的水量感到驚訝

例如  一杯咖啡  需要比倒進壺裡煮的水還多很多的水

根據一本新書  如果加上種豆、包裝等等

一共需要1,120公升的水製造一公升的飲品(咖啡)

相對的  僅需120公升的水就可以製造一公升的茶

1公升罐裝水則需要4公升的水

家用品就更飢渴了  需要幾千公升的水製造鞋子、漢堡、晶片

恩………  真慚愧

突然覺得自己好浪費  整天又是咖啡又是茶的  該好好檢討！

還是單純的多喝水吧
