__Guns, Germs, and Steel: The Fates of Human Societies__ – The National Geographic DVD/Video based on the book by Jared Diamond.
===(This book won the Pulitzer Prize, but is not easy to read in its entirety.) The DVD/video however, is dramatic, outstanding, and profound in topics for discussion and debate. It is free on Netflix; and on Youtube there are 18 brief episodes (about 8 minutes each) spanning all of world history:===
