I originally watched Earth Story when it was shown for the first time on BBC2, and I'm currently watching it again on UKTV History ten years later.
It is truly a brilliant series, explaining every facet of the Earth's many geological processes: such as plate tectonics, subduction, spreading, the carbon dioxide cycle and iron deposition as well as how those processes interact with the planet's meteorology and biology in a complex dance. It also reveals how the Earth is also reliant on and affected by the other elements of The Solar System.
Personally, I don't see how you can get to the conclusion of the previous reviewer. Manning doesn't get involved in climate change, largely because the programme pre-dates the current debate and because the series sets out to be instructive about the natural life-cycle of the planet as opposed the effect of humans on that planet.
Manning is more interested in a planet that's existed for several billion years and is - as far as we can tell at the moment - unique, certainly in this solar system. The fact that humans who currently infest the planet may well cause the whole thing to go pear-shaped is outside the scope of the programme which is great because it avoids turning the programme into a polemic.
All in all, it's an instructive, well-told story that is - as previously mentioned - an example of how the BBC can make great programmes when it abides by the "mission to educate" that was the blueprint of Sir John Reith when the corporation was established.
