I'm having trouble squaring the received wisdom on this with the numbers on this[1] page. Beef is 6 times less efficient than wheat, yes. But it's up to half as efficient as soybeans. Pork is actually a more efficient use of land than soybeans (and almost identical to celery[2], while containing vastly more nutrition). Chicken's nothing special.

- esarbe 7y agoMaybe the unsourced numbers on the page you linked to are plain wrong? I know, it's the first hit when you google, but let's do some more "research". I raise you a Wikipedia! https://en.wikipedia.org/wiki/Edible_protein_per_unit_area_of_land https://en.wikipedia.org/wiki/Edible_protein_per_unit_area_o... According to these numbers, soy beans produce about 16 times(!) as much protein for a given plot of land compared to beef. That's quite a difference. Thanks for the reply! Edit: I hope this doesn't sound condescending or suchalike. I'm really interested what the real numbers are, but the page you linked to (while honestly very intersting; permaculture! No-till-agriculture) is somewhat lacking in credibility. I hope we can find a tabulation that satisfies our curiosity and our purpose.
- dTal 7y agoOh, it's not condescending - like you say I just googled quickly and the beef one seemed close enough to be plausible, so I took a gamble that they were roughly right - To be honest I did the numbers manually on the celery first, then I got impatient. Thanks for the Wikipedia link - although it bears noting that edible protein is distinct from calories, and a good example of the complexity that calorie-focused "bioefficiency" metrics miss.
- esarbe 7y agoGlad I didn't offend! And thanks for the nice exchange - much appreciated!
