And the reason we still use CO2 slaughter instead of something like Nitrogen is because.... They already have machines built for CO2 and just don't want to pay the cost of changing practices.

Pure greed and laziness.

Also co2 is easier because you can fill a pit with it, nitrogen will just float about and disperse.

As far as I’m aware NO~2~ will fill a pit. In the industry I work in NO~2~ leaks are serious threat because the engines that are worked on are in, what is essentially, a cage that you walk down into. I’ve not experienced it myself but heard from someone who experienced it firsthand as you just start feeling sleepy. I know now that it’s because our bodies are sensitive to asphyxiation from CO~2~ but not NO~2~, so as it displaces the oxygen in our lungs you just start getting woozy and tired.

All that being said; I am not an expert. Half this is information from diesel mechanics who work with it and the other half is from random science videos. So take it with a grain of salt.

It’s just heavier??

[–] AnUnusualRelic@lemmy.world 4 points 5 days ago

It tends to be heavier than air, it will therefore accumulate in low places.

Most slaughter houses use bolt guns.

Zero pain, or as minimal amount of pain as possible. Like, microseconds. Because afterwards, the entire brain has been... disorganized.

It's hard to find official statistics, but most definitely not.

It is clear, however, that in the United States today, “CO2 stunning of pigs is the major method that is used in large slaughter plants.” According to unpublished data from the Pig Improvement Company, the use of CO2 gas to stun pigs has increased dramatically in recent decades. In 1999, CO2 was used to stun 2 percent of all pigs and 2.2 percent of pigs in establishments that slaughtered more than 4,500 pigs per day. By 2020, those numbers had risen to 86.2 percent and 96.2 percent, respectively. Today, according to FSIS enforcement records, at least 32 slaughter plants use CO2 gas slaughter systems.

If you assume, that the operator doesn't make any mistakes and is always 100% on point. Which they are not, as has been documented by countless of hidden cameras people have put up in slaughterhouses.

And even then, you are ignoring the immense pain and stress the animals experience the rest of their life before getting killed.

They just know people will buy the meat no matter how much the animals were abused so why would they bother? Even those who see themselves as animal lovers happily look the other way with every purchase. The industry has all the incentives to be exceptionally cruel so of course it is.
