Winter Solstice Part 1: The Spirit World comes to mind, as does The Swamp when it comes to talking about nature, but i'm not sure what exactly you're looking for. you could also try the page on the air nomads. a lot of what aang embodies about nonviolence and respect for nature is said through his actions and beliefs as well.
i'm going to leave post it here in case anyone else has any direct examples. thoughts?
