the issue of bottled water and problems related to it peaked my interest.
as time goes by and we drain natual aquifiers,water and water sources will become a very serious issue.
new sources will be exploited such as Canadian lakes and rives,American lakes and rivers.
Canada will face increased pressure from it's American neighbours to export bulk water...and I predict bulk water exports will be challenged under NAFTA as traditional sources grow dry.
This could lead to huge problems as well as huge de-salination plants that suck sea water to create fresh water...this would over time concentrate more and more the salinity of the oceans leading to further problems...of course that could be offset by melting glaciers and a melting greenland! *grabs a beer and relaxes-prblem solved!*
