I have watched the documentary cutting off the voice and the music, reading the script only. I found the music too emphatic.
It gives the layman a good overall picture of the evolutionary facts concerning our planet.
I was wondering if the message at the end could not be a bit more bold: it is kind of obvious that man has had a hand in transforming the planet and will this not have an impact and will this not create another cataclysmic change like earth has lived through its history?
