How Wolves Change Rivers

[Jim]

 
I know that Wolves are not pets, but it is an animal thing. Anyways:
This video is more of an insight how changing just one thing can have such an affect on other things that are totally unrelated.  Its a good example of how changing one minor thing in the past  (if we could) could change the entire civilization.
 
Also, how changing something now, in the present, will likely have a major change on our future. So, be careful what you want changed.
 
Its good example of the Butterfly affect.

When wolves were reintroduced to Yellowstone National Park in the United States the most remarkable "trophic cascade" occurred.

The only unfortunate thing about that video?
 
THOSE WERE NOT DEER !!!!  They were elk, save for one, little yearling doe that was on screen for a second or so...
