I haven't yet been convinced that giving up meat can help. Specifically, I haven't seen the question of what happens to the grazing land.
If it is left to burn, the carbon it contains cycles grass ➡️ fire ➡️ CO2, particles ➡️ grass, etc
If it's left to rot it's grass ➡️ methane, CO2 ➡️ grass
If it is rewilded the carbon cycles grass ➡️ meat, methane ➡️ predators, etc
If left as it is it's the same, but with us in place of the predators.
I really feel like there is no way of preventing the carbon emissions of grasslands, but at least if they're making meat for us we can work on engineering a way out of the methane release, and people are working on that
And at worst it's not fossil carbon, it's renewable, the carbon emitted is captured again when the grass regrows
There's carbon in the farm equipment, but that's the same in all farming
