That year will mark the end of a 50-year agreement to keep Antarctica, the Earthâ€™s last pristine continent, free of exploitation. Explorer Robert Swan â€” the first person to walk both the North and South Poles â€” is on a mission to ensure that we extend that treaty. With passion and vigor, he pleads with us to choose the preservation of the Antarctic for our own survival.
