Thanks to Hal and Sue for setting me straight on the deer/elk issue. The confusion came from names used by Europeans vs. N. Americans. So, apparently, our elk are called Red deer in Europe. Our moose are known by the name elk across the pond.
Several of you told me this video came out a couple years back. It is used by the Woodland Park Zoo for education. It may have been made by National Geographic. In any case, this is a valuable, factual and well-done short explanation of reason to continue to work on bringing wolves back into a few of our wilder lands, to make them healthier and more complete.
