Well, I don't know whether being poisoned by CO2 is painless. The anecdotal evidence seems to be rather mixed.
The pigs filmed in the Bite Size Vegan's video definitely do seem to freak out when being poisoned by CO2. And the survivors of the Lake Nyos Disaster (when lake oversaturated with CO2 suddenly erupted and suffocated thousands of people and livestock) mention feeling some pain.
On the other hand, many people have been poisoned by CO2 when things go wrong in the wine processing industry, and they generally say they felt no pain. One student at my university is developing a low-cost electronical device for detecting elevated levels of CO2 for his bachelor thesis. He says that human beings can't detect lethal levels of CO2, that countless people have been exposed to lethal levels of CO2, mostly in the wine industry, and that many have died that way.

Do you know that when you are suffocating, struggling desperately to draw breath, the cause of your suffering is not the lack of air, because not having enough oxygen or any other part of air  is literally painless and brings about no unusual sensation whatsoever until you pass out from low blood oxygen level?

Do you know what physiological mechanism that creates the discomfort of suffocation and the feeling of desperate need to draw breath is?

It is elevated levels of CO2 in the blood.


You are totally full of the most vile depraved shit.

Well, go tell that to the people who were poisoned by CO2 in the vineyard industry. If they felt something, they would have probably run away before they could be poisoned.
