Do you know how much water it takes to produce a pint of beer (20 gallons), a 2-liter bottle of soda (132 gallons), a pair of Levi's stonewashed jeans (500 gallons), a cotton t-shirt (700 gallons), a hamburger (630 gallons)? These are some of the examples cited in an article in yesterday's WSJ by Alexandra Alter. More and more companies are looking at their water "footprint," and ways to stop using so much water.
36 states are anticipating water shortages by 2013. It's a hard thing to calculate a water footprint, because there are so many other factors to consider. There are no clear standards for what should be measured in arriving at a water footprint. I predict we will be hearing much more about this in the months and years ahead. Predictions are that if current trends continue, there will be an additional three billion people living on the earth by 2050.

I feel like I've dropped down a hole and come out in the 1970s giggle. I well remember all those scary predications then. I think we should concentrate on taking the water we have in the ocean and utilizing it. Afterall, we are in a water shortage with 3/4's of the earth covered in water. It doesn't make sense does it?
