Oh dear - another red herring. Natural respiration simply returns the same carbon to the atmosphere that was already there and was very recently (and that's really the point) absorbed by the plants at the base of the food chain. Obviously respiration (by itself) does not increase the overall level of CO2 in the atmosphere. It is releasing fossilized carbon that has been trapped for millions of years and the carbon that has been in the process of being trapped for decades or centuries in the woody stems of trees that increases the overall CO2 in the atmosphere. Respiration doesn't do that - at least not much - although an increasing amount of the human diet is derived from fossilized carbon and obviously industrial food production processes contribute as well.
