It doesn't matter how much CO2 is produced naturally. CO2 that is naturally produced is carbon neutral because it's part of the carbon cycle. That's why when you burn biofuels it is supposedly better for the climate because those carbon emissions came from the carbon cycle.
The CO2 that has been sequestered in the earth in the form of fossil fuels is not part of the carbon cycle.
