* Jake Sully chooses to stay on Pandora: After being paralyzed in the real world and finding love and purpose as a Na'vi, Jake decides to permanently transfer his consciousness into his Avatar body. This means he can never return to Earth.
* The RDA is defeated: The human military is driven out of Pandora by the combined forces of the Na'vi and the remaining human rebels.
* Neytiri and Jake become leaders: Neytiri, Jake's Na'vi lover and a powerful warrior, becomes a leader of her people, alongside Jake.
* The future of Pandora remains uncertain: While the immediate threat of the RDA is gone, the movie doesn't explicitly reveal what happens next for Pandora or its inhabitants. It leaves open the possibility of future conflict and challenges, but also hints at a hopeful future for the Na'vi and their planet.
The "end" also suggests the following:
* The importance of environmentalism and respect for nature: The film emphasizes the need for humans to learn from the Na'vi and their deep connection to their environment.
* The power of love and empathy: Jake's transformation is driven by his love for Neytiri and his growing respect for the Na'vi culture.
* The potential for humanity to change: Even though Jake chooses to stay on Pandora, his actions inspire others to stand up for what is right.
The ending leaves a sense of hope, but also a reminder of the ongoing struggle for survival and the importance of protecting the natural world.
It's important to note that the story of Avatar is continuing with the release of sequels. So, while the ending of the first movie does provide closure, it also sets the stage for further exploration of the characters and themes.
