It's not a question of volume, it's balance that is important. If there's balance between oxygen used in fossils burning and oxygen produced in photosynthesis - the source of extra carbon dioxide in the atmosphere is not human related.

It was roughly in balance before we started pumping large amounts of CO2 into the atmosphere. Our emissions have upset the natural balance and are increasing the amount of CO2 in the atmosphere.
