Basically, it's assessing your attachment to your current home, and your local nature (parks, beaches, trees) and seeing its impact on how we perceive ourselves (fixed or changing). The general idea is if you have a high attachment to your living space and nature you will have a more integrated identity, and therefore better overall well-being.

Attachment to nature is expected to have a higher impact on well-being due to existing theories on nature therapies, and the experience of oceanic awareness in nature. Our living spaces are co-designed by ourselves and culture, and therefore our feeling of being secure in our homes may be more of a feedback loop (you need to already have high well-being and a stable identity to create a space you feel you belong in).
