I grew up with an uncle who raised steer and the sheer amount of land it took just to grow the corn and grass they ate was astounding. The animals also needed constant medication to stop them getting each other sick due to diet and proximity. So that's the regular non organic, non grass fed/finished reality. With human population the way it is that kind of farming is pretty much the only way we can sustain eating meat in the amount we do.

I wonder, realistically, how much land it would take to produce our meat, at the current rate of consumption per capita, to grass feed/finish all those animals.

I have never even heard of a cow calf operation operating as a feed lot. Every single cow calf operation I have ever seen, heard of, ect feeding pasture or grass hay.

And you did we were I said I disagree with feed lots right?
