In 2154, humans have depleted Earth's natural resources, leading to a severe energy crisis. The Resources Development Administration (RDA) mines a valuable mineral unobtanium on Pandora, a densely forested habitable moon orbiting Polyphemus, a fictional gas giant in the Alpha Centauri star system. Pandora, whose atmosphere is poisonous to humans, is inhabited by the Na'vi, a species of 10-foot tall (3.0 m), blue-skinned, sapient humanoids that live in harmony with nature and worship a mother goddess named Eywa.
