Of all the eco-hypocrites, Celine Dion's water usage is one of the most astounding. Back in May '08 we posted "Water: Celine Dion Uses 6,500,000 Gallons Per Year". This fact stayed at the front of my mind (partly as a counterargument to a certain someone who hinted I should see C.D.'s show).
kottke.org tips us to a chart at Good magazine that has some interesting factoids i.e. a glass of wine uses 31 gallons of H2O to produce vs. 20 for a pint of beer, etc.
