I think the author is interpreting paleo as "high protein" whereas most people doing paleo are "low/no grain". Some people focused primarily on trendiness seem to insist their low carb diet is paleo no matter how heavily processed and weird it is (like those weird soy bar things)

I pretty much don't eat grains but almost certainly vegetables are more energy intensive than grains so maybe my paleo salads are killing the planet almost as well as the vegans eating processed soy products and baked wheat products all day.

Then again no matter how thinly you slice it theres not a lot of calories in a carrot so even if volumetric intake looks near vegan most of my calories might be coming from meat/fish/oil sources.
