The following excerpts are from ‘How Exactly Wolves Change the Course of Rivers’ by Ray Molina of yourdailymedia.com Mar. 1, 2014
…Trophic cascade is when the behavior of top predators have a trickling down effect on their environment. Let’s call these predators the “one percent.”
The one percent may be vicious killing machines who think only of themselves, but even bad intentions could have good outcomes. We are finding out that their murderous ways can be useful in controlling the over population of herbivores that are eating more than their fair share, which leaves little for a multitude of other animals lower on the food chain.
Eventually there will be plenty of wolves, perhaps even too many, and at some point we may need to protect the rest of the food chain from these top predators.
But like most things, if not everything, there’s a time and a place.
I do wonder about whether or not the Ecosystems would have just found a new way to balance themselves out over time. Who knows how long that might have taken though, or maybe it’s currently happening in ways we cannot yet witness.
The main culprit of our Eco failures is you and me through our destruction of habitats through land-developing and hunting and pollution. We really blew it, and now we’re trying to cut our losses by celebrating animals that repair our mistakes.
In the video below, Author/Activist George Monbiot describes to an audience at TED the effects of Wolves that were reintroduced into Yellowstone National Park in the mid 90′s.
He describes how the wolves, in a relatively short period of time, have transformed the landscape and allowed more varieties of life to flourish. And wolves did it in ways we never expected.
It’s a humbling reminder of just how connected life on this planet really is.
The original TED talk by George Monbiot, gives numerous examples of how “rewilding” our ecosystem can give us back the earth our predecessors had the privilege of experiencing.
NOTE: There are “elk” pictured in this video when the narrator is referring to “deer.” This is because the narrator is British and the British word for “elk” is “red deer” or “deer” for short. The scientific report this is based on refers to elk so we wanted to be accurate with the truth of the story.
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.
