In the second part of this four-part epic series, Steve Simpson explores our complicated relationship with the natural world. Attracted by its beauty and fearful of its dangers, Australians are forever locked into a battle with the elements. But this isn't just a story about coping with drought, deluge and dangerous animals. Steve looks at how we protect the environment whilst harvesting land and ocean for its resources. In a stunning opening scene we join aerial fire fighter Rob Laver in South Australia's Deep Creek National Park executing a controlled burn - a small fire now, we learn may control a catastrophe later.
