VIRTUAL WATER WEEK
We’re coming up to World Water Day again on 22nd March. Water use is definitely flowing up the political agenda. So I thought I should focus on virtual water this week. If you add all the water needed to grow crops and feed animals for ingredients and materials, that’s the virtual water needed for a product. The figures are quite startling.
I’ve reported on virtual water comparisons before, but this is the most comprehensive I’ve seen so far. It was published in a poster insert with National Geographic magazine in April 2010.
