I don't know if you have ever been to the website "mediastorm", but if you haven't, you should check it out. These are 5-20 minute video clips by photojournalists showing some pretty hard-to-watch documentaries on what's going on outside "our world". Here's a couple that I found just outstanding.
The first one focuses on the people in Africa who are dying of Aids as you read this. I know that we've all seen and know what is going on over there, but in this 12:06 story, you'll be shocked.
The second one is the most horrifying photographs of Chernobyl in Ukraine described by the UN as "the greatest environmental catastrophe in the history of humanity."
After you watch these, watch some of the others. All of them are well done. This site is really easy to use too.
