There was an interview I watched recently that said the whole factory animal farming industry basically relies on maintaining a distance between the consumer and the farms, as the average consumer doesn't want to think or consider how the meat arrived, etc.
Also what is jaw dropping, is the scale of slaughter of many different animals. Perhaps none more than chicken. I don't remember the exact number(can easily google) but it is massive. I do think we need to consider how all this scale has helped drive down costs and availability of food which further helped alleviate human hunger around the world. Though, I feel sad every time I hear of a story of a barn fire at one of these farms killing like 50K chickens at once. Or the recent bird flu cases, where they need to cull all the birds to stop it from spreading. And I remember the stories during the onset of Covid, where they had to basically cull huge numbers of animals, because restaurants, etc would shut down for the near future.
One other thing that has felt awful to me is that of mink farming. I don't understand how that business still exists(some places it's banned, but not everywhere). Especially with all the textile technology, and means we have in today's world, it seems morally wrong to subject these these animals to suffer needlessly, and also get affected by these flu's, etc. which leads to massive culls.
