And during that same time period, that water also helped produce nearly 14 tons of that lovely organic matter that seems so hard to find for the poster in another thread, and leather, and in some cases, milk, etc. etc.. The manure alone has a tremendous impact on the reduction of those chemical based fertilizers so many on here rightfully discourage use of.
One pointed question begets another: 2000 gallons of water worth eliminating 14 tons of chemical fertilizer? Now how about if the majority of that water is also given back?
We all have to eat and watering a cow provides that and quite a few more beneficial by products, and the water is mostly returned, much of it within that organic material.
Watering a lawn produces... more lawn.
Seems to me that the target of the article overshot the mark a bit. Instead of pointing directly at the food supply as a major water abuser, perhaps simply suggesting a few less flushes, showers, or lawn sessions would be more appropriate unless the objective was actually reducing meat consumption.
