Quote from Tresor:
I was not accused of anything.
Since you apparently don't understand what a Chewbacca defense is, it's when you use an argument which has nothing to do with the case. Here's an example:
T: The same land area of grass and cabbage absorb more CO2 than the same area of rainforest!
B: Ummm... sounds unlikely, why?
T: Duh! When you stand in a rainforest do you see much light?
B: Ummm... all things being equal, the light hitting both is the same even though you're standing in the shade.
T: I wasn't talking about grass in different weather conditions, like in Scandinavia!
B: (Forehead slap.)
Tresor might have very well referred to replacing forest with rubber trees, banana trees, x-mass trees or tomato plantation. The kind of the plant mattered NOT.
Tresor's claim (and scientific fact) would still remain true that new plants have advantage over old plants as far as CO2 capture goes.
Your sticking to cabbage is of course not a ... Chewbacca defense
Well no, it actually isn't, it's a quote from you actually.
And given that I looked it up, you're also wrong, or at least wrong about cabbages and tomatoes, probably incorrect about rubber trees and banana trees, hard to say about x-mas trees, and absolutely 100% wrong about cabbages.
Overall you're not quite correct, that new plants have an advantage over old plants as far as CO2 capture goes -- in fact, this has been studied by the Department of Energy which analysed carbon sequestration among carbon in undisturbed vegetation, carbon in recovered vegetation, carbon in crops, and time for vegetation to return from disturbed to recovered state.
In fact, it takes at least 15 years for new plantings, such as reforestation efforts, to return to their normal, recovered state and crops don't even compare.
They were kind enough to release the raw data here:

Not that this has any impact on, well, anything -- since atmospheric CO2 is increasing, temperature is increasing, and CO2 absorbs IR (as we've covered). There's just no escaping this fact.
