I found this story really interesting. It demonstrates my point on peoples view to water and its disposability. We live in a very self dominated society, ie me first. As a result while some horded bottled water others were left with nothing. I has to be questioned why not just by loads of empty bottles and fill them up from the tap as the water supply hadnt yet been affected !?

There should should have been a better push for conserving water, and recycling. I just dont understand why this wasnt done !
