The traditional interpretation of history has focused largely on human factors. Yet the natural environment has also shaped history since the dawn of time. This series reveals for the first time on television how geology, geography and climate have had a far more powerful influence on mankind than has previously been acknowledged. With passionate storytelling and extraordinary HD camerawork, this series combines bold ideas with a new science, geo-determinism, to form an original version of human history. Discover why societies have succeeded or failed, and how the environment has influenced every aspect of our history from art to industry, religion to war, world domination or collapse. This series overturns preconceptions about our nations and our cultures to offer a new perspective on who we are today.
