As I read some questions here, I noticed that a good reason for something living to be somewhere is often survival. But what are the cases when it isn't? What could be a good main reason for a living being to stay in a place that isn't survival? Of course, the living beings can survive in such a place, but what makes them stay wouldn't be to survive.
One example would be that Mankind can try (and succeed) to live in the desert only to prove a point, or gather luxury ressources, etc, but it's not really the best place to live in the world.
- The living being is human or human-like: it has society, economy, and all of the 'futile' ways to spend its time;
- The living being is closer to an animal, or is one: it searches for food and sleeps most of the time.
PS: Unfortunately, I can't think or find a good tag for this question... So feel free to edit it :)
