I gonna intercept here for a bit. The Problem with "shutting down single farms" is, that this virtually has no effect at all. The entire conventional farming sector is quite fucked up. Everything gets optimised for the highest possible efficiency. This means, that everything that falls out of set norms will be eliminated.

What I mean by this is, that, as example, piglins that didnt grow that well are simply killed by the farmers, because they can't be sold. This happens because no farmer will give you the same money for a piglin that has half the weight of the others and is much more likely to get targeted by the rest of the group. Since its illegal to kill piglins without a reason the farmers do it by themselves and then dispose them with the piglins that die when during, or shortly after, birth. Nobody notices, and it is not possible to control this (at least not realistically). The problem is, that this whole system so fucked up that by shutting down single farms you only combat symptoms of the system and not the root cause. By this I do not want to say, that we have to shut down the entire animal farming sector, but that we have to drastically reduce the intensity of the sector to shift production to quality instead of quantity.

Source for the stuff I said: I grew up on a farm (not with piglins) and had to work in a piglin farm for 4 weeks. I have seen the stuff I said first hand and I devinetively did stuff that I'm now deeply ashamed of retrospect. The stuff I saw also matches the tuff I have heard from other sources.

You're right to question the boiling. I was thinking of death by suffocation in heated steam. Boiling is not the technically correct term.

Here are some more sources that nearly all livestock live in factory farms: [Our World in Data, PETA,]; there are a lot more I can find searching the web but they mostly seem to link back to the Sentience Institute's research. OWiD's is based on SI's research, and I suspect PETA's claim is based off SI's as well. More importantly, I haven't found any claim that the proportion is lower than 90%, or even anyone challenging SI's figures. Do you have reason to doubt this? And if so, can you find any source? It seems plausible to me just based on the fact that factory farming is vastly more efficient than other methods, and most people aren't picky about such things. Just as a prior, I would expect that the vast majority of livestock are found in the most efficient types of farms.

Without any attempt to describe the methodology used for their estimates.

I mean they literally have their calculations available right there as an easily-viewable google sheets link. And the data source is clearly stated: "these estimates use the 2022 Census of Agriculture and EPA definitions of CAFOs to estimate the number of US farmed land vertebrates who are in CAFOs ("factory farms")."

You’d be trying to get that particular farm shut down, get laws passed to prevent that from happening. But you’re not doing that

Who is not doing that? Me specifically or animal rights people in general? I don't see why shutting down a particular farm would be very helpful, the scale of the problem is incredibly massive; passing laws would be much more effective. I would like to see laws passed, though, to stop these kinds of abuses. What would make you think I am not interested in that?
