Well then, put a plastic bag over your head and a rubber band around your neck and breath your own very safe CO2 for an hour.CO2 is not a dangerous gas, CO is. Without CO2, we wouldn't be here.
We breathe air that is 21 percent oxygen, and we require oxygen to live. So you might think that breathing 100 percent oxygen would be good for us -- but actually it can be harmful. So, the short answer is, pure oxygen is generally bad, and sometimes toxic. To understand why, you need to go into some detail...
HowStuffWorks "Is it harmful to breathe 100-percent oxygen?"
Well that idiotic post blew up in your face...
Exactly, in concentrate, CO2, O2, N2 are extremely dangerous. It doesn't exist in these forms(concentrate) in nature though. The last I checked, the earth's atmosphere is approx 78 percent nitrogen, 21 percent oxygen, with trace elements of CO2, argon, neon, and methane.
