Check out Stu Hamilton’s blog post on the Aquatic Informatics website about World Water Day 2013.
“To mark World Water Day at Aquatic Informatics we watched the movie ‘Last Call at the Oasis’. In discussion about the issues raised by this movie one of our senior developers expressed surprise at the magnitude of the water footprint for everyday products.
For example, the water footprint for a t-shirt was given as 700 gallons!
I don’t know whether the notion of accounting for your water footprint will catch on or not. A few years ago the idea of calculating your carbon footprint got quite a bit of press and even though carbon calculators have never caught on the notion that your carbon footprint matters seemed to stick. Equating energy use with a carbon footprint is intuitive – if I turn on a light my footprint grows whereas if I walk to work my footprint shrinks.”
