Don't have any videos to suggest, but what about the power of the Internet itself to connect people and help them coordinate action? It is clear that our beloved leaders have other things to do than deal with the most pressing problems facing humanity: global warming, water shortages, poverty, etc. It is only the Internet that, I believe, will allow enough people to not only educate themselves quickly enough but also to connect with others in meaningful ways and to act in cooperation and concordance with each other. MoveOn and other anti-war organizations have shown how to do this with regard to that particular issue.

As a source, not of video, but of ideas and inspiring products, I recommend the Buckminster Fuller Institute.
For the first time in history it is now possible to take care of everybody at a higher standard of living than any have ever known.
Only ten years ago the "more with less" technology reached the point where this could be done. All humanity now has the option to become enduringly successful.
R. Buckminster Fuller, 1980

"If success or failure of this planet and of human beings depended on how I am and what I do, how would I be? What would I do?"
