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 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.

Author: Roger - Dr Roger Prentice

Now I write, teach & coach mainly about interfaith as inter-spirituality - and how we can grow closer to our True Self. . As anyone who knows anything about IPF will realize my energy is curtailed - so I am concentrating primarily on 'inter-spirituality'. . In the past I would have said that: . 1) I run courses and give talks at conferences and in universities and colleges in the UK, China, USA, Canada, Scandinavia etc. . 2) I provide materials, outlines and lessons for Schools. . 3) My range of interests include personal development, learning and teaching, photography and film, the arts generally, spirituality and educational practice and theory. . 4) At the same time I continue developing the human-centred studies SunWALK PDS (People Development System) - a whole-person, high-achievement model for individuals, and for use in, NGOs, schools and other organizations. . 5) The key question that continues to animate me and my work remains, "What is it to be fully and positively human?" . Contact me via onesummit AT gmail DOT com (replace At with@ etc.). . All good wishes Roger (Dr Roger Prentice) . For those interested; My first degree is in English and Education. My masters is in Adult and Community Education. My doctorate presented a new holistic meta-model of education called SunWALK.
