Besides which, that water isn't lost; in the Netherlands, it either sinks into the soil to eventually become ground water again (after which it's reused), or it ends up in the sea via canals and rivers. It's not like we have a water shortage in NL, not yet anyway. Besides ground water, there are several rivers passing through NL coming from the Alps, sometimes to the point of overflowing. Really, the only thing waste…
Scientifically-speaking, is any water "lost"? Thinking back to those pictures of plains and mountains with a big circular arrow in my seventh grade science textbook: couldn't you say that even the water used by crops, turned into coke, and consumed by humans is eventually returned the ecosystem in some form or another?
In plenty of areas where water is needed, the time it would take for the big circular arrow "water cycle" to replenish it is so long, it should be considered a finite resource.
Ars Technica had a great article about this a few years back, likening "peak water" to "peak oil": http://arstechnica.com/science/2010/05/not-just-oil-us-hit-p...
