The Resources Development Administration, or RDA, is the largest single non-governmental organization in human space. Its power is such that it outmatches most Earth governments in wealth, political influence, and military capability. RDA's environmentally harmful mining operations on Pandora and the RDA SecOps' destruction of the Trees of Voices and the assault on the Omatikaya Hometree had led into a war between the RDA and the Na'vi.
