How long does it take for the trees to evolve to grow shorter? To have a phyllotaxy which is relaxed and following a less complex in mathematical structure! Looking at all the destruction, deforestation, etc; trees may not decide to grow any taller any more. When all the sunlight they need can be easily obtained at lower height, why would they want to grow any taller?

will they evolve? will we be there to see? will we let them to go that far?
