We need each other

And when I think of all the things the people there told me, I realise that the other lessons that Antarctica has thrown up all point this same way: It is only when you are forced to rely overtly on the people around you—and people in far off bases who you'll never meet—that you remember how fully we rely on each other back in the real world. It can take being in pure emptiness to remind you to let go of your hubris; and it can take being blocked by the power of nature to remind you how precarious our existence is and how tenuous and temporary our mastery.
