@ahelwer Meat doesn't require much "carbon", and the whole process is cyclical, just like the water cycle (also fake numbers for beef). A typical cow needs roughly 0.8 to 1.0 acres of grass to sustainably forage feed continuously. One acre of grass produces enough oxygen in a day via carbon sequestration and photosynthesis to provide 40 PEOPLE worth of oxygen. Which more than offsets this. The cows breathe 10-30x per minute (call it 20) with a lung capacity of 7.0 L verses a human males 6.0 L 12 - 20 (call it 16). Based on these numbers, a pasture raised grass fed cow is a net negative carbon user during its lifetime. The only logical critique after this is slaughter, which is more of a critique of industrialization and its carbon utilization. Considering cows have been raised and slaughtered since before written language records, I highly doubt this is a carbon intensive process by itself. One could easily criticize the industry, but to do that without criticism of industry writ large is agenda driven and duplicitous.
