The End of the World - Part 2

I like life's little ironies -  the same day I post a review about the apocalypse, TED publishes a video with the editor of a science magazine on 10 ways the world might end. A list I might add that is uncannily similar to one found in the Pocket Guide to the Apocalypse. 

The talk is about half an hour and the speaker, while no oratorical genius, has his moments.
