Surviving the Extreme (2x1)

:

In the high Himalaya, yak-herder Thokmay Lowa and his small group steer his herd through one of the region's extreme mountain passes. In the Canadian Arctic, traditional Inuit communities still forage for much of their food. In the Mato Grosso, as a result of deforestation, the region's microclimate has changed. In the blistering Australian Outback, cattle ranching requires a lot of space. The only way to efficiently round up the herds on these vast farms is through the use of helicopter cowboys. Deep in the Siberian interior, survival is tough. But climate change is opening up a new niche for the human inhabitants of this region.
