The oxygen in the air does not "finish" because it is continuously replenished through processes like photosynthesis, where plants produce oxygen, and atmospheric circulation that redistributes it around the Earth. Therefore, the balance between oxygen production and consumption ensures that there is a constant supply of oxygen in the air.
