“We poetically construct our identity as human beings, together with our values, largely through reciprocal relationships with animals. They provide us with essential points of reference, as well as illustrations of the qualities that we may choose to emulate or avoid in ourselves. Any major change in our relationships with animals, individual or collective, reverberates profoundly in our character as human beings, in ways that go far beyond immediately pragmatic concerns. When a species becomes extinct, something perishes in the human soul as well.”
