Quick additional note on your last bit for 1- you're really kind of proving my point about individual behavioral/consumer level change acting as a release valve (though you admit it's subjective). There is no way forward on climate that isn't structural and doesn't hold powerful organizations to account. That doesn't happen through the true believers opting out. Or put another way, it is ethical to not eat meat and it relieves guilt, but the political goal should be to make it harder to eat meat and even remove it as an option.
> There is no way forward on climate that isn't structural and doesn't hold powerful organizations to account.
There is a lot of truth in that. As it is now though, some meat eaters will say that businesses need to stop murdering animals, while people controlling and working at those businesses will say that they're only doing it because people buy it. It's an easy and convenient view to hold, because it let's everyone put the blame on someone else, while not having to do anything themselves.
The companies' position would only make sense if they weren't spending so much on advertising, lobbying, and other attempts to reinforce the structures that lead to the levels of meat consumption we have now.
I'm saying it is critical for anyone who cares about this to do something. Organizing to get laws changed, subsidies stripped/rerouted, and other structural changes takes effort from everyone who has a stake in this. We just disagree on what it is that is critical to do.
