id be more concerned for the major inland american cities RE water shortages.. 99% of australians live on the coast and like everyone has said this is an exaggerated problem that effects the inland farming communities (ie ~1%-5% of the pop.) to a much greater extent than the urban centers. The urban centers abide by water restrictions during summer to cover mainly for the agricultural areas..major US cities in Texas are draining the table water supplies at a rate that will leave them depleted in about 40 years..and supplying a large city like that with water just isnt viable...im no tree hugging hippy but from a commercial point of view real estate in large inland cities in America seems to be a poor investment in the long term. i would suggest that they will be abandoned or severly downsized by the time you pay off your morgage (if you have one)...either that or something else bad will happen..
my negative 2 cents
