First with the carbon, now with the water. I wonder how long until we start measuring our oxygen footprint. I mean, the plants can only produce so much O2. If we don't watch our breathing we will run out.
BTW... This article suggests drinking tea instead of coffee and wearing polyester instead of cotton and turning vegetarian to reduce your water footprint.
How much water it takes to make...
1 kilo of beef: 15,500 liters of water
1 glass of beer: 75 liters of water
1 hamburger: 2,400 liters of water
1 cup of coffee: 140 liters of water
1 cup of tea: 30 liters of water
1 cotton shirt: 2,700 liters of water
