i know what i said was wrong, but what i meant (literally and not metaphorically this time) was if we were to adapt to it, its would mean there would be less CO2 produced because there wouldnt be as much oxygen to produce CO2 from exhilation etc.

and more oxygen (without adapting to it this time) would kill, you cannot live on pure oxygen, you can for a small amount of time, but thats it.

For the third time, that is INCORRECT. For example, some SCUBA systems only cycle pure O2.

A pure O₂ atmosphere is highly toxic and you would die from it.

I don't know what the fuck you're talking about, because Scuba systems use a compressed Oxygen/Nitrogen mix.

Not if it was still the same partial pressure as we are used to.

No, you'd die. It's like negative G's on the brain. Too much oxygen overwhelms the body, and it'd kill you.

The same amount of oxygen kills you?

You said "same partial pressure". What the hell does that even mean? More Oxygen, less pressure?

You're still inhaling much, much more oxygen than your body is used to.

Educate yourself, please.

Okay? If you added more oxygen to earth's current atmosphere is the what-if here. Not if you totally changed how it is.

You haven't read the wiki page, have you?

Same partial pressure means same amount. It means you can take away the 80% N2 and replace it with some other non-toxic gas and still breathe fine. In fact, you can just take away the 80% N2 and leave it, assuming you give the person enough time to acclimatize to the lower total pressure. At any rate, 11% more oxygen is not toxic. Deal with it.

^^

Read the question, man. He said that putting more oxygen into the atmosphere can lead to death, which is true, unless you changed the pressure, yeah. I've never heard the term "Partial Pressure" before.
