FAKE NEWS - Nitrogen is already 78% of the Earth’s atmosphere, far more than Carbon Dioxide, for example. Increasing it a bit is NOT going to kill anyone.

< sigh >

DO NOT attempt to breathe pure nitrogen.

I repeat DO NOT ATTEMPT TO BREATHE PURE NITROGEN. IT WILL KILLYOU.

Not because nitrogen is poisonous ... it isn't.

Pure nitrogen will kill you because it contains no oxygen.
