alt Hacker NewsThat link shows that twice as many emissions are attributed to farm stage vs land use change. And fta: "Farm-stage emissions include processes such as the application of fertilizers and the production of methane in the stomachs of cattle."
So not sure there is much for me to respond to you given that.
They always start with a false equivalency anyway, comparing stuff like cane sugar with cow meat, that's just extra dumb.
I don't have proper calculation, but when you add up all the processing and extra requirement to grow high protein crops, you are actually not very far from meat cost.
Which makes sense because if meat was so inefficient, then vegetal protein replacement should be much cheaper, but they are not.
