This video was posted on Tuesday.  Despite being half an hour long, it has been viewed 50 million times.  It's time for you to watch it.

In the interest of full disclosure, there has been some criticism of Invisible Children, although it doesn't amount to much in my view (no charitable organization is perfect).  Some of the criticisms are silly (yes, the Ugandan government is corrupt; the film doesn't claim otherwise).

But the problem depicted in the film is accurate.  You can read the Invisible Children's response to some of these criticisms here.

If nothing, the film should serve as an introduction to the problems facing the Ugandan region.  And what you can do about it.
