TEXT A
　　I used to look at my closet and see clothes. These days, whenever I cast my eyes upon the stacks of shoes and hangers of shirts, sweaters and jackets, I see water.
　　It takes 569 gallons to manufacture a T-shirt, from its start in the cotton fields to its appearance on store shelves. A pair of running shoes? 1,247 gallons.
　　Until last fall, Id been oblivious to my "water footprint", which is defined as the total volume of freshwater that is used to produce goods and services, according to the Water Footprint Network. The Dutch nonprofit has been working to raise awareness of freshwater scarcity since 2008, but it was through the "Green Blue Book" by Thomas M. Kostigen that I was able to see how my own actions factored in.
　　Ive installed gray-water systems to reuse the wastewater from my laundry, machine and bathtub and reroute it to my landscape - systems that save, on average, 50 gallons of water per day. Ive set up rain barrels and infiltration pits to collect thousands of gallons of storm water cascading from my roof. Ive even entered the last bastion of greendom -installing a composting toilet.
　　Suffice to say, Ive been feeling pretty satisfied with myself for all the drinking water Ive saved with these big-ticket projects.
　　Now I realize that my daily consumption choices could have an even larger effect –not only on the local water supply but also globally: 1.1 billion people have no access to freshwater, and, in the future, those who do have access will have less of it.
　　To see how much virtual water 1 was using, I logged on to the "Green Blue Book" website and used its water footprint calculator, entering my daily consumption habits. Tallying up the water footprint of my breakfast, lunch, dinner and snacks, as well as my daily dose of over-the-counter uppers and downers - coffee, wine and beer- Im using 512 gallons of virtual water each day just to feed myself.
　　In a word: alarming.
　　Even more alarming was how much hidden water I was using to get dressed. Im hardly a clotheshorse, but the few new items I buy once again trumped the amount of water flowing from my faucets each day. If Im serious about saving water, I realized I could make some simple lifestyle shifts. Looking more closely at the areas in my life that use the most virtual water, it was food and clothes, specifically meat, coffee and, oddly, blue jeans and leather jackets.
　　Being a motorcyclist, I own an unusually large amount of leather - boots and jackets in particular. All of it is enormously water intensive. It takes 7,996 gallons to make a leather.jacket, leather being a byproduct of beef. It takes 2,866 gallons of water to make a single pair of blue jeans, because theyre made from water-hogging cotton.
　　Crunching the numbers for the amount of clothes I buy every year, it looks a lot like my friends swimming pool. My entire closet is borderline Olympic.
　　Gulp.
　　My late resolution is to buy some items used. Underwear and socks are, of course, exempt from this strategy, but 1 have no problem shopping less and also shopping at Goodwill. In fact, Id been doing that for the past year to save money. My clothes outrageous water footprint just reintbrced it for me.
　　More conscious living and substitution, rather than sacrifice, are the prevailing ideas with the water footprint. Its one Im trying, and thats had an unusual upside. I had a hamburger recently, and I enjoyed it a lot more since it is now an occasional treat rather than a weekly habit.
　　(One gallon =3.8 litres)
