If it is common knowledge that shutting a garage door with a running ICE vehicle inside will kill you, why do you think so many people think 1 billion ICE vehicles aren't bad in the atmosphere?
"But tires"
Ban all vehicles over 5000lbs to start without a specialized license and extremely heavy fees to have them. EVs are dropping in weight daily, ICE vehicles have been increasing in weight to dodge policies. One is a means to an end, the other is a means to profit.
Profit for few vs humanity's existance.. which should we choose?
This is a bad argument. Your conclusion happens to be factual, but it doesn't follow from the premises.
Being in an enclosed space with an internal combustion engine will kill you because of the CO buildup, and no, that doesn't happen in the open air. CO does oxidise to CO2 eventually, so it doesn't just keep building up in the atmosphere.
The main harm caused by burning fossil fuels is the CO2, which is wreaking havoc on the climate and will kill billions - but not by poisoning them.
Why would it not be considered poisoning? It is a substance that is effectively killing people.
Yeah the enclosed space thing is about carbon monoxide though. Just find it to be easier for people to understand when people believe the earth is thriving because "there are more people now than ever." Not caring that everything is dying around us.
Medical dictionary:
Definition
Poisoning occurs when any substance interferes with normal body functions after it is swallowed, inhaled, injected, or absorbed.
So if you drown, it would be, if you get crushed, I would say it doesn't fall into poison
