If you haven't already watched any of the episodes, I can highly recommend the Earth series that are just as stunning as any of the David Attenborough Planet Earth (and other) series.
I am familiar with much of the geological processes of the early Earth ( Snowball Earth , Siberian Traps , Pangaea , Plate Tectonics and so on) and the various extinction level events in the past but still found it to be an enjoyable documentary series. Chris Packham is renowned for his views on climate change so it is not unexpected that the series focuses on the same processes that could affect the future, yet the series is more about the violent historical events of the past and how life evolves. I found it really interesting.

Watched the last episode of the Earth series last night (episodes can be downloaded from BBC iPlayer but I used the "tv catch up" on my Sky box)
As expected, this was about human activity and how it has affected the Earth since the hunter-gatherer turned to farming. Interestingly, Chris Packham explained how previous Extinction Level Events were natural disasters (meteors, volcanic, temperature swings) and each time life had returned, different species had evolved that were different prior to the disaster (such as the emergence of mammals after the dinosaurs 66 million years ago) After following the series, the last episode reminded everyone of how each disaster had unfolded and then compared it to the current situation, and how humans are basically conducting an experiment on a global scale which has similarities to past events. I thought it was a sobering comment.
Definitely worth watching the whole series.

I think I might be interested in this, but. . . . I don't have a tele, do not pay for a licence, so therefore I cannot access BBC iplayer. Maybe it will come to Youtube.
