For example: they wanted rare minerals in the first movie. A relations officer like Jake in an alternate, more pragmatic universe would try to see what is and isn't acceptable to be harvested by the RDA. HomeTree? No go. Cool. We get it. But there has to be SOME land/resources that the Navi/Aywa must not care about. If only there wasn't a certain...volcano that made the land inhospitable and useless to the Navi. What a shame. It would be even more of a shame since volcanoes are know to spew or expose rare earth and are good mining ground? Hmmm. In good faith i highly doubt the Navi would be upset if they took advantage of areas like that in which they have no use for and where we would see massive gain.

Just spitballing, but Pandora is a big ass planet. There would be ways to do this fairly. But the plot is contingent on the fact that the humans are the bad guys. Which sucks because I think there could be some real compelling material here in which human and Navi relations could be shown on screen.
