The second article, entitled "Ecologists warn the planet is running short of water," discussed the end of the era of "cheap water." Well, that prediction may be more true for those living in the north where water is currently plentiful and underpriced, but tell that to the inhabitants of water-impoverished nations who are paying up to 20% of their incomes for water and pay exponentially more per gallon than we do in the developed world.
Reference is also made to a study by David Zhang, a geographer at the University of Hong Kong, in the US National Academy of Sciences journal that analysed 8,000 wars over 500 years and concluded that water shortage had played a far greater role as a catalyst than previously supposed.
