In avatar, Jake's colleagues want to destroy the "home tree" of the Na'vi to get the valuable mineral that is located under the tree. Destroying the tree doesn't necessarily ruin the Na'vi's habitat because the Na'vi go around and are parts of many different parts of their surroundings and the place that they treasure most may not be their home.

A similar event that happened in history was when the europeans first got to the US and they weren't respectful to the natives so some native americans fought back.

A similar event that is happening right now is all over the world. Even now, in countries all over the world, the natives in the countries are often the poor ones, the ones that have a harder time in society while the newcomers try to squash the natives' culture.
