I also just find it funny that part of the excuse Jane gives for why the Trolls need to be controlled population wise is because they could outnumber humans and "take too many resources" away or whatever. Just ask Jade to make the planet bigger. It's really that simple. She could just make everything slightly bigger overtime thus solving whatever made up problem Jane had with the trolls. There'd always be enough land because Jade had the power to just MAKE more land by breaking the laws of physics with two fingers.
