How wolves can alter the course of rivers

Wolves will travel to drink from a river. But could the presence of wolves lead a river to change its behaviour?

Check out this video: http://blog.ted.com/2014/02/18/video-how-wolves-can-alter-the-course-of-rivers/

 

In his TED Talk, George Monbiot poetically explains how reintroducing wolves to Yellowstone National Park after a 70-year absence set off a “trophic cascade” that altered the movement of deer, sent trees soaring to new heights, attracted scores of new animals to the area (think: beavers, rabbits, bears, bald eagles and more), and stabilized the banks of rivers making them less susceptible to erosion. Above, see that story set to music — and howls — by SustainableMan.org, who took the audio track from the talk and laid it over beautiful nature footage. It’s a glorious glimpse of how deeply the natural world is interconnected.

  1. The more we interfere the more we destroy. If something in nature is an inconvenience we try to get rid of it, and at the same time it creates a new problem. Wolves are important and absolutely beautiful animals.
