Wolves…….
This is truly amazing…….how we change the world……
Remember when the wolves were introduced back into Yellowstone
National Park about 20 years ago?
There was a lot of debate about whether or not it was a good thing.
I don’t know your thoughts on this but have a look at this video clip.
How often do we wonder, what the heck difference does one animal
make in the greater scheme of things?
Well, here is the answer!!!
Sit back and enjoy this amazing video on how just one animal has
changed the environment.
