Didn't see your comment until after I added my edit. I am aware that water is a troubled resource in many parts of the world and that it's imperiled for many different reasons. I think uhsguy makes the beginning of many good points that could be made about why showers pale in comparison to many other things that threaten our water supply. I'd like to try a mist shower and I bet there are many different situations where a super low flow shower could be a great thing. I should give them credit, they waited for the second paragraph to call water and power scarce. Neither is scarce and yet still man kinds desire to consume both in an almost limitless quantities compared to supply. I admit that I get irked when the opening of a long essay drops some silliness along these lines. I don't really have a problem with his solution or the goal of conservation of resources, I just find Malthusian bullshit irksome and he got my goat.
