How The Earth Changed History takes a look at how geology, geography, and climate have influenced the rise and fall of cultures and societies in our history as early as the beginning of civilization through to the modern industrial age. How The Earth Changed History looks at different forces that have had an impact on our history including the forces of deep earth, wind, water, fire, and the human planet.
The DVD is narrated by Professor Iain Stewart and the documentary walks us through the far corners of the world from Iceland to Egypt. The section on water explains how civilizations grew around areas of water which makes perfect sense and then goes on to explain in the deep earth section that these areas of water in some cases are right on fault lines. The section on wind discusses how the wind has influenced sailing and of course that has influenced trade and exploration as well. The fire section talks about how the discovery of fire allowed metalsmithing which allowed for better weapon manufacture which in turn influenced who won wars, etc. The human planet section talks about how we (people) have changed the earth since we've discovered how to use all the previous forces of the earth. While some of the things have had a positive impact, like irrigating crops, many have had a negative impact, like pollution.
