Oh stop pulling an OP. Unnaturally high levels of CO2 can be dangerous after long term exposure - hours in an industrial environment that already has a bunch of other crap in the air. Carbon Monoxide from your home furnace at high levels knocks you out and kills you in 30 minutes. Still not the same.
CO2 absolutely will kill you though, it’s just not as bad as CO
