This is a compelling video, not the least reason for which is the fact that although the science in it is hard-won, the message it offers is one of those simple, "Of course, it must be that way" revelations. 

The video is an excerpt from a George Monbiot TED talk (well worth the extra ten minutes or so) on the topic of "rewilding," defined in Wikipedia as, "…large-scale conservation aimed at restoring and protecting natural processes and core wilderness areas, providing connectivity between such areas, and protecting or reintroducing apex predators and keystone species."

I wonder if there's something primal in us that recognizes the reality, the truth of nature, when we see it. It seems to me we realize almost instinctively that ecological systems must be knitted together in these complex webs because we existed as part of it for nearly our entire evolutionary history. And there's a voice that counsels us - even as we refuse to listen - to embrace natural ecosystems, not alter and then "manage" them. Most of us have learned not to listen to that voice, but exposure to this kind of research can help us "unlearn" it.

The information in this video could hardly be more topical and pertinent, considering that the U.S. Fish and Wildlife Service is currently proposing to delist (remove from the Endangered Species List) the Gray Wolf.
