Tonight we explore man’s relationship with fire. We begin by embarking on an extraordinary encounter with this terrifying force of nature – a walk right through the heart of a raging fire. Fire has long been our main source of energy and we show how this meant that the planet played a crucial role in Britain’s industrial revolution, whilst holding China’s development back. Along the way we dive in a mysterious lake in Oregon, climb a glacier of salt, crawl through an extraordinary cave in Iran and take a therapeutic bath in crude oil.
