I did read the article and it lists multiple inefficiencies. And I didn't claim that the article was about halting factory beef farming, so I'm not sure where you got that from. There is one line in there about Americans meeting their protein and fat intake requirements if cows were solely fed on grass. Great rant on humans eating grass, but what does that have to do with anything? No one is saying you need to eat grass. The article is about the direct human consumption of grain vs. production of grain, feeding and growing cows, slaughtering them, shipping them, then consuming them.
