Books are cool. Also undervalued. I think you should read these puppies:
East of Eden, John Steinbeck
Brave New World, Aldous Huxley
Into the Wild, Jon Krakauer
The Clock of The Long Now, Stewart Brand
The Road, Cormac McCarthy
Middlesex, Jeffery Eugenides
Also these, which I am currently in the progress of reading:
Cradle to Cradle, William McDonough and Michael Braungart
The Story of Stuff, Annie Leonard
No Impact Man, Colin Beavan
