28-year-old Barney Swan has accompanied his father, Robert, on multiple expeditions, including a 600-mile walk to the South Pole that his father was unable to finish in 2017. While the son will join his father on the "Undaunted: South Pole 2023" expedition, scheduled to conclude in January 2023, Barney is cutting his own distinctive path to sustainability and pulling the world along with him. From growing up as a London boy transplanted into rural Australia, to his current effort to regenerate a section of the world's oldest rainforest, Barney has a unique perspective and plenty to say.
