You don’t have to remove co2 permanently to be useful, for instance, each individual tree may eventually become gas again, but if you double the size of the forest, you’ve doubled the amount of gas not currently in the atmosphere. As long as that forest exists, that carbon is captured, even as individual trees get swapped out for their gaseous counterpart.
