I know a fair bit about forests from restoration work. What forests do to store carbon is to produce a lot of soil. Twigs, branches, leaves, they build up and compress and compost.
Where is that supposed to happen in this vertical arangement? The litter will be cleaned up and put where?
There's a factor callled green waste, where lawn maintainence waste creates a bunch of methane as it rots. And doesn't form soil. So there are important details.
