A human-only definition is:

"Liveability is typically defined by the extent to which a place can attract and retain its population (homes, jobs, transport and the like); one with a good quality of life that makes provision for children and older people, clean air, green spaces, social and spiritual belonging, heritage and cultural sites."

How can this be extended to include nonhuman lives?
