These are a couple of Wolf related things I found.

WOLVES BELONG

in our world, and their survival 
serves as a barometer of how well man is treating
the environment overall. As part of the wild world,
wolves play an important part in the balance of
nature, and without them, all of nature suffers.
To some extent, hearing the call of the wild things
at night lets us know that the world is doing better
than if everything were silent.

WELCOME TO WOLVES

"If all the beasts were gone, men would die from a great
loneliness of spirit, for whatever happens to the beasts
also happens to the man.
All things are connected.
Whatever befalls the Earth
befalls the sons of the Earth."

- Chief Seattle of the Suwamish Tribe
from a letter to President Franklin Pierce
