Dominions of fizz: the carbonated-drinks industry and public health [pdf]
You keep using this word "used", I do not think it means what you think it means...<p>Fresh water is one of those strange things, where consumption is not necessarily destruction.  You 'used' a glass of water that you drank this morning, then excreted it over the rest of the day as urine and water vapor where it became an input for another part of the cycle.  The water did not go away when you consumed it, and in this case most of the water 'used' in the production of a litre of sugar-enhanced carbonated water was never lost.
