I hope this never is taken down by youtube, but I'm posting it here because I've been promoting this very vid since it's arrival in 2011. It is the best and most thorough explanation of what agenda21 really is that I've ever come across.
It's an hour and 23 minutes long, but break it up into 15 minute intervals if you have to. There are some places where you might think it's rather "dry going" but this is not a dry subject, it's a subject we should all be paying closer attention to than we are at this time. We need to stop daydreaming and we need to stop polluting our everyday thinking with political crap and start seeing the real happenings around us that almost go unnoticed if you aren't well informed and if you aren't paying attention.
If I ever find another video of this talk, I'll post the link here. You know how youtube has been lately - - deleting everything of importance, so I'm surprised this is still up and running, actually. Glad it is though.
