Rumen is a component of digestion--it has nothing to do at all with the overall % of biomass converted to calories as an overall comparable metric between plant harvest and animal harvest.
Dude was talking about biomass conversion and you're talking about how an animal digests food.
Also, you complete moron, as I said before arid lands can be farmed by permaculture methods and there are examples in India, Africa and the US that do exactly that.
