This Will Shatter Your View of Apex Predators: How Wolves Change Rivers

Have a look at this amazing video showing how one species can have a massive cascading effect on the entire ecosystem in which it lives… and even alter the geography of the area.

This may be one of the most important conservation concepts to come out of natural science in the last half century. The thing about this case study is that the same can be applied to apex predators around the world: lions in Africa, tigers in Asia, sharks, bears and wild dogs are all species sitting at the top of their respective food chains, creating stability amongst the species they prey on and maintaining the health of plants animals right down the trophic ladder.

The sad part is that some of these apex predators are in decline, sometimes jeopardising ecosystems on which they and other species rely.

Human/wildlife conflict is a reality of growing populations around the world, and the fact is that we need to learn to live beside wildlife if we are to maintain our wonderful thriving ecosystems in the future.

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.

    Wolves are my favorite animals in the wild! They are brave, noble and intelligent animals! Because of these qualities from their wolf originated the best friend of man - domestic dog.

    More people need to see this. Maybe then they might just get that ,the wolves are majestic animals. They help ALL of the ecosystem ! They are not the destructive ones like some people think. Congress & the Senators need to see this. Maybe then they will stop allowing this majestic animal from being killed.

  4. A must see video for anyone concerned with the impact wolves can have on an eco-system.
