> And meat animals use less resources per pound of protein that vegetable sources.

What? There's literally hundreds of scientific articles out there that establish the opposite, e.g. [1]

Edit: Where do you think the protein in cattle comes from? Isn't it… plants? That the cattle eat? Once eaten, the cattle expend some energy to live and then we kill them for meat.

By not eating animals, you cut out the middleman and waste less energy.

That premise is only accurate if you are planning to have everyone consume livestock feed. If that is the plan, then you shouldn't be fixating on beef, you should be going after almost all crops we grow, which produce just as few calories per acre as beef, and even lower protein per acre. Depending on where you draw the line, your argument effectively requires all farms to only grow a small number of very high calorie crops like field corn and potatoes.

I'm sorry, but you are completely wrong. There are many plants that produce much more protein per acre than beef: https://en.wikipedia.org/wiki/Edible_protein_per_unit_area_o...

Edit: I can't reply to child anymore, max comment depth reached. Anyway, I think my work here is done :) I am not demanding we stop growing lettuce, I am demanding we stop raising cattle for proteins. We can keep growing lettuce for vitamins / minerals. As for the so-called "absurd fake figure" for protein/meat land utilization, that figure is from 1970's. I'm willing to concede that number may have risen slightly with the use of antibiotics as growth stimulator ;)

P.S.: Legumes are a whole family of plants, divided into 11 major types.

You can't say "you are completely wrong" and then support that by showing I am right. You showed 5 crops that produce more protein per acre than an absurdly low fake figure for beef. That's precisely what I said, that we would have to cut down to just a small handful of highest value crops. 5 is a small handful, we currently grow thousands. You know full well lettuce produces fewer calories and less protein per acre than beef. But you are not demanding that we stop growing lettuce, just beef. Your demands are inconsistent with the premise you use to support them.
