Iain Stewart investigates a new and controversial energy rush for the natural gas found deep underground. Sometimes, this is right under the places people live in. Getting it out of the ground involves hydraulic fracturing - or fracking. Iain travels to America to find to find out what it is, why it is a potential game changer and what we can learn from the US experience. He meets some of the people who have become rich from fracking as well as the communities worried about the risks.
Welcome to the Collision Zone – the fiery unpredictability of Indonesia’s volcanoes at one end, the massive Himalayas at the other and millions of years of tectonic tension in between. The collision zone of the old world is about to be the hub of the new. India, the Himalayas and the island arc of Indonesia - these lands will form the centre of the world’s next supercontinent. A story unfolds—a tale of where the earth has been and what the earth shall be: a whole new world that we’ll barely recognize.
(PART 2) A team of experts and explorers venture into the Danakil desert in Northern Ethiopia to investigate the incredible geology of the area, and to find out how the people and their animals survive in the hottest place on earth. Kate Humble investigates how tough life is for an Afar woman; Steve Leonard wants to learn about the relationship between the Afar and their animals, and to help with animal medicine where he can; Dr Mukul Agarwal looks at the health issues faced in this most hostile of environments; earth scientist Dougal Jerram looks at the extraordinary volcanic activity of the region and the part it plays in the bigger geological picture of the Rift Valley; and biologist Richard Wiese searches for extreme life forms in the boiling soil of a massive volcanic fissure.
It’s a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
