I did watch that video. probably a dozen times. it gets posted often. I shouldn't be expected to debunk an argument that isn't made.

I rewatched* it after I made my comment though, and it does not establish what they claimed. it doesn't cite sources**, and it's primary thesis is "it's complicated"

edit(s):

* i actually listened to it. but just now, after i made this comment, i scrubbed it and i found:

** they do some pretty hard-to-see and also hard-to-research citation in the form of citing academic papers in the bottom right of the screen around the time they are making the claim. and let me tell you, poore-nemecek is the basis of the lca analysis (which i could have guessed), and that lca analysis is flat out bad science. it's certainly not a compelling reason to be vegan.
