my old boss had an idea - "bury trees".

There's a bit of nuance to be filled out, like challenges of forest plantation monoculture and so on, but it always sounded quite practical to me. Iirc the idea derived from "coal".

Better yet sink them in the deeper parts of the ocean. Below a certain depth wood loses its buoyancy due to the pressure levels of the water. (I think)

Of course, ships sink all the time.

Unfortunately we don't really have enough deep freshwater to bury them in. Below the thermocline freshwater has little oxygen and logs can last till the turn to fossils.

With saltwater it's a bit trickier because it's decently oxygenated even to depth and there is a lot of life dedicated to breaking down wood in the ocean. If you can get it to sink into the muck it lasts a lot longer though.
