Watching CNBC documentary on water - really interesting factoid about the amount of water to "produce" a product (eg instead of carbon footprint - its a water footprint), some of the figures really caught me by surprise eg;
- it takes 713 gallons to make one shirt,
- it takes 630 gallons to make one hamburger patty
- it takes 53 gallons to make one egg.
Amazing figures when you consider the agricultural unsubsidized rate for usa water is about 1c per gallon.
