Nowhere in the history of the world has "collected wood" ever grown back. Those stoves are absolutely not efficient burners of wood. They do nothing to reduce exposure to combustion byproducts, not only that, but as a result of their poor design, contribute more air pollution. See the soot on the tile behind the stove? Do you like cooking on the floor? Does this stove help you think your flight isn't impacting the planet?
