"Who Is The Earth? Moral philosopher Mary Midgley delivers a talk concerning differing and changing attitudes to our planet and our environmental responsibilities"
I really enjoyed this lecture on the how (mainstream) western philosophy has little to say about our moral relationship with the Earth and other groups. Well worth listening too. I found this at "iTunes U" on my iPhone. I am sure it is also available for downloading to an iPod, etc.
