Use your power to do whatever it takes to secure for humankind an enduring place on this little blue speck in the universe - our only hope.

No creature on Earth ever has organized themselves in ways that we have, with the capacity to alter the nature of nature the way we have.

For humans, the Arctic is a harshly inhospitable place, but the conditions there are precisely what polar bears require to survive - and thrive. 'Harsh' to us is 'home' for them.
