Good Online Videos

Hello! I’m looking for a video that can explain the causes and effects of violence in a society. Preferably, it shouldn’t have blood, deformity, limbs falling off, nudity, swearing, or anything disgusting. In fact, I’d like the sort of video you wouldn’t be afraid to show your 8 years old son or daughter. I’m a bit squeamish.
I’m also looking for generally family orientated animations of the web, 'cause they’re great. Again, no blood, deformity, or swearing etc., etc…
Thank you!
