well if you had to live without oxygen and just carbon dioxide, you would suffocate pretty quickly

lving without food and water would let you live for a bit longer

though maybe not as i'm not really sure how long it would take for everyone on the earth to use up all the oxygen in the atmosphere??

but we really never could run out of oxygen because plants take in the carbon dioxide we breathe out and turn it back into oxygen

so idk

i'm overthinking this ahahha
