NG Live!: The Power of Photography to Witness

Photojournalist Marcus Bleasdale wants to make people angry; as angry as he is about Africa's first world war and the surprising way in which we are funding this violence.

The National Geographic Live! series brings thought-provoking presentations by today’s leading explorers, scientists, photographers, and performing artists right to your YouTube feed. Each presentation is filmed in front of a live audience at National Geographic headquarters in Washington, D.C. New clips air every Monday.
