||As produced by and originally aired on the BBC, the epic-length documentary miniseries HOW THE EARTH CHANGED HISTORY rests on an unusual thesis. It argues that various natural forces - including climate, geology and geography - have dramatically guided human history, to a greater degree than many have traditionally thought possible. The program then goes on to discuss the impact of the said forces on societal elements including the success or failure of various civilizations, the nature and presence of art, war and religion, and much more. In building its argument, the program interpolates such elements as on-location footage shot around the world, incisive commentary and epically-scaled storytelling. As a special feature, the package includes "Filming in Extremes," an interview with program creator Iain Stewart.
