How wolves change the rivers.
TED Talk by George Manbiot
Rate 5/5
This TED talk in showing the effect that a small population of wolves made on Yellowstone Park. It showed in a trickling effect how the wolves have a correlation to the geography of the national park. Showing that when the wolves killed deer who grazed the fields bare, trees started to grow. By trees growing, it strengthened the shore line of rivers with their roots, thus causing less erosion and giving food to beavers who make dams creating a bigger ecosystem for fish and other wildlife.
This article affects me by showing how large of an impact one thing can make upon an extremely large ecosystem.
