Yes, I think this issue of how many people you need to get on board with the vision/​goals to make some change happen is key (and perhaps a crux). I agree the number of people needed to implement a change might be huge (all the farm workers making changes for various animal welfare things) but think we probably don’t need to get all of them to care a lot more about nonhumans to get the job done. So in my view often a small-ish set of people advocate for/​research/​fund/​plan some big change, and then lots of people implement it because they are told to/​paid to.
