Theory:Doctor Who television discontinuity and plot holes/In the Forest of the Night


 * The Doctor's theory and supposition that the trees don't burn due them collectively acting to withhold Oxygen is dubious at best. Trees don't consume oxygen, they produce it. Simply arranging for the trees in a given area to not produce oxygen once a fire is lit would not extinguish the fire, as there is still oxygen already present. Failing to add more wouldn't extinguish it. Think fires in office buildings, apartment complexes and the like. No trees around to continually produce oxygen, yet fires still burn.


 * Once they realize what they are up against and the disaster that has befallen them, Clara says "If you can't save them all, save who you can. The Tardis. It's a lifeboat, isn't it? Not everybody has to die." They make their way back to the Tardis, and inexplicably Clara says that the Doctor has to leave without the kids, and without her and Danny. Who exactly was she anticipating that the TARDIS would be a lifeboat for?
