There's an interesting thread I blogged on over at Beyond Green about the amount of water in a latte. How much? Over 200 liters for one cup, according to WWF (via Marc Gunther's blog.)
Does this mean we should stop drinking lattes? No, but it does mean we should start thinking more intelligently about water usage. One commenter mentioned that the data requires no action. That's true on the consumer level perhaps, but awareness and knowledge breeds action upstream with producers.

I think these numbers a bit high. I know the source is waterfootprint.org, there site also says that a single slice of wheat bread uses 40 liters of water. Can this really be true? How is this being calculated?
