      It might not get rid of oxygen but it would become really really small in amount compared to other gases.

      No it wouldn’t as we get most of our oxygen from the ocean (by cyanoacteria) đŸ™‚

      Scientists think that we are breathing more of another gas, carbon dioxide, than ever before due to global warming, so getting rid of more of the environment might mean we breathe even more carbon dioxide!
