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.

I saw this before. It was good to watch again. I think all schools should be showing this and telling how all animals and biodiversity beneficially affect the health of our Earth.

I just can't understand why they have such a a need to wipe out the wolves. It seems more determined than just the usual greed factor. Maybe it's because so many of us revere and love the wolves and they just want to crush us. I just wish there were more of us wolf lovers in positions of power!

Just yesterday, and numerous times before, I have submitted comments to various gov't agencies about how the wolves in Yellowstone helped stabilize the elk population there, and thus allowed the riparian system restore itself, by stopping the elk from browsing on saplings!
Thanks Sheryl.

This was a wonderful video, finally someone has recognized the importance of the wolves and how they play a part in the ecosystem. Thanks for sharing now if only other's can gain this knowledge the wolves would stand a chance.

This just goes to prove that the wolf has a vital role in the eco system - we need the wolves!
Thanks Sheryl.

all creatures great and small
they just discovered your food is only as good as the soil it was grown in
the problem,insects "the garbage men of the earth" are being kept from doing their jobs,and the soil is so much worse for it
biodiversity is our greatest gift,and we are killing it
ty Dandelion,as always important information

And if the wolves can do all this in the mere fact of living and being in a certain area then is there any doubt of the two legged human impact upon the lands? By our actions we can do great destruction or we can learn to live in a balance with our environment.....we'd all be the better for it.

Is true Tasunka, it is a factual statement of our foods having less nutrients in them than before these toxins were used on the soils in such abundance. They have measured the nutritional value of our foods from the 1950's onward and the value we are gaining from eating our food is going down.

Down payment on death at work for both, animals and humans. Probably their plan. Picking up on Dan Partlow's comment above, I too have often wondered just WHY do they persist on this horrendeous wolf slaughter? No way they would not know the importance of the wolfves for sustainable environment, so it must be the opposite. They do know well about it and is why they try to prevent it, just another measure of so many other ways to slowly depopulate living beings.
They cannot openly slaughter Native Americans anymore, although they've continuously tried it in subtle ways to let them rot to death, so by going after their sacred wolves they hurt and harm the indigenous peoples at the same time- how convenient.

Fantastic video Dandelion.
This needs to be shown on T.V stations in
the Midwestern states of Montana, Utah,
Nevada and Colorado. In New Mexico and
Southern California. In any state that allows
the killing of wolves and wolf packs.
Thank you for posting here.

Thank you, Sheryl. Wolves are necessary to ALL LIFE, when the Fascists figure that one out, it will indeed all be too late. It must stop and NOW. They hate wolves because they are connected to eachother and to us. We learned from nature, wolves in particular, at the beginning of our kind. In them, the Fascists see what we once were and could be again. They do not want that for humanity, they want everything for themselves and us as fragmented, fractured, divided SERFS. So, yes, it goes far deeper than just mere greed.

We're hell-bent on killing all the wolves, when they are all gone, maybe we will realize how important they were, every living thing is on this earth for a reason.

Beauty & the "beast". Interesting how ecosystems are working together, with the presence of wolves. Thank you Dandelion! Have yet to visit the Yellowstone National Park.

Noted. Thanks so much for posting, Dandelion. I just signed more petitions and sent letters today in defense of wolves. When I was a toddler, my mom used to read me a story called "El Lobo" and I have never forgotten it.

Wow that was such an informative video. Complex ecosystems dependent on relationships are not a backdrop for silly human dramas that can be mindlessly exploited without consequence. The howling at the first and end was great too!

Noted and shared. Excellent video and very informative. I had seen this somewhere else and maybe it was Thom Hartman as someone else mentioned because I could tell I had not shared this; so it wasn't on youtube that I saw it. I, too, have asked and wondered why people seem so hell bent on slaughtering wolves; because it's not just on this continent, it is happening everywhere in the world where wolves roam. I have been so surprised by this. Thanks for sharing this Sheryl.

It's not nice to mess with Mother Nature. We need Wolves and are part of nature and should be left alone.

this needs to be played in the bedrooms of all the political idiots who are trying and allowing these beautiful creatures to be killed so ranchers can profit until their way of thinking is changed..also i think they know this but just enjoy destroying everything beautiful...
my boy enjoyed the beg of the video as I did..such a beautiful sound
