Thirsty Thursdays: Another Water Post
I have a thing with water. It is one of those all-important resources - essential to life, but finite on this planet. Well, an article in Science recently analyzed the water footprint of the human race. Apparently, the U.S., China, and India together use over one-third of the fresh water! Ok, we're only number three...despite having a mere 5% of the population. This analysis also accounted for "virtual water," or that used indirectly - such as the processing and transport involved in getting food to your table. While the article claims that agriculture uses "a whopping 92% of all fresh water" consumed annually, the UN FAO puts the figure closer to 70%. Either way, agriculture is a huge drain, so it presents an unparalleled opportunity to increase the efficiency and reduce the overall use of water.
