I think people are missing the point a bit here. This work takes away an excuse for eating beef. Thanks to this work, people can no longer kid themselves that eating beef is innocuous because they bought the happy-cow version. Now they should know that eating beef means choosing between more climate emissions or more animal cruelty, but there’s no guilt-free version.

So just to be clear, beef being grass fed is more about the flavor and quality of the meat than it is about ecological friendliness. And the livestock having a less shitty life is kind of just an ancillary benefit of that.

To me the most interesting part is the following with bold

They found the emissions per kilogram of protein of even the most efficient grass-fed beef operations were 10 to 25 percent higher than those of grain-fed U.S. beef — and many times as high as those of plant and animal alternatives.

It’s still leaner and tastes better.
