How Earth Made Us: Human Planet (2010)
Professor Iain Stewart tells the epic story of how geology, geography and climate have influenced mankind. Using spectacular images, illuminating science content and compelling narration, the series discovers how four different planetary forces have shaped human history. In this program, Professor Iain Stewart explores the most recently established force, humans. It is easy to think of the human impact on the planet as a negative one, but as Iain discovers, this is not always the case. It is clear that humans have unprecedented control over many of the planet's geological cycles; the question is, how will the human race use this power?
