Re: water for food

C'mon, get serious.  500 liters of water for a kilo of potatoes?
100,000 liters for a kilo of beef?  Strains credulity, well past my
breaking point.

Whoever is responsible for this chart owes all of us a closer look at
how these figures were derived.

Looks cooked up to me, in a plot to pile on animal agriculture in
general, and beef producers in particular.

Beef takes a bum rap.  Under grazing systems, cattle utilize forages
unsuitable for human consumption, reducing tillage, benefitting water
quality and erosion control.

I challenge anyone to justify these remarkable estimates.  Until someone
does, all of us should consider them BS.
