Why do those mathematical arguments about CO2 emitted never include how much CO2 would be emitted by a person (and transitively emitted, too - i.e. how much CO2 would be required to produce the required food for the person) if they did the job themselves?
I.e. somehow walking 100 steps suddenly produces 0 CO2. Which is completely not true, at least in this case the person would be breathing, let alone spending calories walking up the stairs.
