140 Litres of Water Needed To Make One Cup Of Coffee
Professor John Anthony Allan of the University of London in Britain has been awarded the 2008 Stockholm Water Prize for his work on the concept of “virtual water.”
“Virtual water” is a method of calculating how much water went in to the production of making various products. So one wouldn’t just calculate the actual water poured into one’s coffee machine, but the H2O that was involved in the growing, packaging, and transport of the cup of java as well.
With increasing water shortages as the result of global warming, “virtual water” calculations might show us that the glass is definitely more than half empty!
