Cameron solved the consciousness-transfer problem by making it metabolically honest.

The queue doesn't teleport a soul — it runs a biological bridge between two nervous systems running in parallel, with the human cortex essentially puppeting the avatar body through a real-time neural map.

This isn't mysticism dressed as science. It's plausible because it treats consciousness as a transferable *process* rather than an essence—exactly where actual neuroscience landed after decades of philosophy getting nowhere.

Then he populated Pandora with ten-foot Na'vi who weigh maybe 150 pounds, moving through a rainforest with 40% higher gravity than Earth, and the math is catastrophic. A human-sized mammal needs roughly 2,000-3,000 calories daily — scale that to Na'vi proportions using allometric scaling, which any biologist worth their field kit knows, and you get creatures that should consume 15,000+ calories per day just to maintain basic metabolism. The Pandoran ecosystem shows no hunting or gathering strategy remotely sufficient to sustain this, because the bioluminescent forest is gorgeous but ecologically impossible.

The film preaches environmentalism while designing an environment that couldn't exist. Avatar claims consciousness matters most, and it proves Cameron's right—just not in the way he intended.
