Every caver in Texas and most high school students know that inhaling really high carbon dioxide levels are not good for you. But carbon dioxide is not some evil gas, it's naturally produced in your body as part of oxidation of organic compounds you consume. The problems arise when you can't ge

If you come to a cave with a skull-and-crossbones posted at the entrance, carbon dioxide is probably why. Don't go in without breathing apparatus. I know of one at least one right near the highway to Bustamente. If I recall correctly, they have sort of mazes at or near the entrances that prohib

There's more to it than that. CO2 has some regulatory control over your breathing (e.g. breathing in a paper bag to stop hyperventilation). It also impacts the pH of your blood which can really screw up your day. There may be more, but those are two things I remember from biology class. Too muc

The problem with carbon dioxide is not that it is toxic per se, but that in high enough concentration in the atmosphere it prevents the lungs from off-gassing CO2 from your body to make room for more oxygen. You essentially suffocate because you run out of oxygen, not because the carbo
