I don't even know what this means. The oxygen we breathe has been on the planet for 4+ billion years. We breathe it again and again and again. It's not being produced or consumed in any meaningful sense.
It does get converted between O₂ and CO₂ by a number of processes, but this framing tries to scare the readers to think mining will start slowly suffocating them.
