Volcanos produce a tiny fraction of all the CO2 produced naturally so comparing man's production of CO2 to that low source number is going to make man's output seem huge.
Respiration of living creatures produces 220 Billion tons of CO2. Compared to that, man's 30 Billion tons is about 14%. Not tiny but not huge either.
Now if we could just get all living creature to hold their breath, permanently, - problems solved.
