I've read, but can't find the figures sustaining it, that vegetarian diets are more efficient per acre, but less efficient per gallon of water. The kind of fruits and vegetables humans eat consume lots of water, whereas the food for cellulose-eating cattle demands much less, to the point where a calorie worth of meat would use less water than a calorie worth of human-feeding greens.

If anyone could find back-of-the-enveloppe figures to vindicate or debunk that claim, I'd be glad to read them.

I guess this could theoretically be true somewhere, but in the US—one of the biggest consumers of meat—cattle are fed corn, which is one of the most water-consuming things to grow. 60% of corn eaten in the US is animal feed.
