Douglas Adams: Parrots, the Universe and Everything

Video

In this video from way back in 2001 Douglas Adams explains quite precisely, in his meandering, idiosyncratic way, why we are endangering our ability to live on Earth as a result of a perfectly logical progression of evolution and thought.

Not to mention that the video was worth watching for me just to hear one of my most admired authors speak a few more words.  And of course, as should be expected, his stories are quite entertaining.
