“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.” – John Muir

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable “trophic cascade” occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.

Narration from TED: “For more wonder, rewild the world” by George Monbiot. Watch the full talk, here:

  1. How amazing who would have thought that one specie could do so much. Imagine what we could do without interference. It would be mind blowing.

  2. Have you all taken leave of your senses? There was a huge fire at Yellowstone and now it is recovering it has nothing to do with the wolves. This is an UN Agenda 21 program to re-wild America. When famine hits are you going to eat the wolves or are they going to eat you? The deer are gone and the elk are next. Wolves only eat one third of their kills. So is it no wonder that other animals are coming in to eat the left overs. Did you not hear the narrator …he is probably not American and he no doubt is working for the UN Agenda 21 program.

    1. Right.
      I first found out the extent of the land grabbing on my own here: (two weeks of bills) (four weeks … … )

      Scroll through, and pick out things like..
      HR 4003, H.R. 4049, HR 4018, S 2031

      **Note** they rarely have TEXT attached to the bill. And I can just say right now 2013 was filled with THOUSANDS of these! I know cause I wrote on damn near every one until reaching burnout and sick of Feinstein ignoring everything I say and sending me email attachments (PDF’s) lol with her Traitorous Talking Points. It’s really a waste of my time to write congress anymore, Boxer, Pelosi, Feinstein, Matsui — it feels like writing the ENEMY.

      but ya also get weird ones: As of 02/18/2014 text has not been received for S.2028 – A bill to amend the law relating to sport fish restoration and recreational boating safety, and for other purposes.

      Again no text….

      They did this all last year, THOUSANDS of bills with no text!!!

      So even when you watch the house and senate they still keep you in the dark.

      For awhile I would type a message to the representative on EVERY one of these bills, something to the effect of, “I smell the STENCH of Agenda 21” , or “Yet another Agenda 21 bill with no Text” — Other popvox users have taken note, as Agenda 21 seems to be MORE in the public eye that it was — say this time last year. I know they took note cause when I first joined popvox, the admin said people were complaining about my cussing. Yes when I first got in there I was literally CUSSING at my reps on THOUSANDS of bills. (when I first found popvox It was like a dream come true, all these asshats in one box, all the bills and crap in one box.) I told the popvox admin I would try to tone it down, but I couldn’t guarantee it wouldn’t happen again. (it hasn’t but I admit I haven’t been there in months) There was a great release inside me knowing my messages are going to the reps and calls them a MF’ing oath breaking traitor among many other things I pointed out.

      My point here is TWO FOLD.
      1. For those still talking to their reps… POPVOX can really help track all their dirty oath breaking unconstitutional bills, acts and bla bla.

      And finally, I emphasize the utter plethora of bills. (not just Agenda 21) I would spend an 18 hour day every so often reading and commenting on EVERY BILL. At the end of the day I would feel like utter crap, completely drained and just horrible. But I would notice patterns, like Democrat + missing text + bill that takes something away. I got some Fire for Republicans as well, it’s just not fresh in my mind at the moment–Go learn their patterns, and then when nearly any subject comes up you can speak with Confidence, instead of asking questions, Cause You already KNOW the gig..

      Maybe readers here have already done this? Anyway, I don’t see the point anymore, my reps don’t listen, except in an ENEMY of the US Constitution kind of way.
