But it is true that if I walk into a forest and eat a wild grown apple, that CO2 is then from and in the normal carbon cycle and not any added fossile carbon.

Perhaps it would be better if I clarified my statement as GHG-(CO2 equivalent)?
Plants do their best to suck up all the CO2 in the atmosphere. Yet CO2 is being added to the atmosphere faster than photosynthesis can capture it. This is why CO2 levels are rising. Human activity contributes a lot to the addition of CO2 (and equivalent greenhouse gases) and plants can't keep up with us.
Yes, but fossile carbon is out of the carbon cycle, stored underground until we dig it up? This is a fairly fundamental pillar in the discussion around environmental impact of GHG emissions?
No, I'm saying that this is irrelevant when comparing means of personal transportation...
The fact remain that the biological food chain is carbon neutral. As I already said, and as you also mentionend, it is the industrial production chain that is not.
