Series 2 Episode 1 Surviving the Extreme

In the high Himalaya, join yak-herder Thokmay Lowa and his small group as he steers his herd through one of the region's extreme mountain passes. In the Canadian Arctic, 63-year-old Minnie Nappaaluk and her granddaughter Eva embark on one of the most hazardous expeditions for food: the mussel harvest. In the blistering Australian outback, the only way to efficiently round up cattle herds on vast farms is through the use of helicopter cowboys like Chris Weyand.
