Neil Halloran’s amazing data-driven documentary. 18 minutes long, but it puts the scale of the losses into mind-boggling clarity. Watch it. Fear the implications. Decide to do something about it.
There’s also an experimental, interactive version (doesn’t work on mobile platforms).
And as a bonus:
The Uppsala University Conflict Data Program
Explore the casualties of modern conflicts – the world is getting better, thanks to everyone willing to work for it!
