I just saw this Youtube clip that claims it takes 200L of water to make a latte. Is that true?
http://www.marcgunther.com/2009/02/25/the-anatomy-of-a-latte/ Provides a writeup on the number. In this case of the water seems to come from tropical rainstorms that rain on coffee fields and the issue isn't that big.
Here’s the breakdown, by liters, of the water needed to make that latte:
0.1 for the water itself
2.5 to make the plastic lid
5.5 to make the paper cup and sleeve
7.5 to grow the sugar
49.5 to feed the cows that make the milk
143 to grow the coffee
That adds up to more than 200 liters of water to make a latte.
