My point is simple, modern man is much more destructive to the "natural" scheme of things.
In the case of the woodland caribou (lake superior caribou) there are several causes for its demise.
of those causes the most dramatic have modern man as the root cause.
As far as the passenger pigeon, I'm fully aware of its demise from the world. I was using it as an example. Who ever killed the last one or the last thousand of them is not the one who eliminated the species. The species was already doomed at that point. Much like the woodland caribou in the great lakes area. A few left, a fraction of what it once was. Now to blame the wolf for its demise is rather short sighted. for sake of discussion lets say modern mans action caused the population to drop 90% from highs 300 years ago and now years later the wolf is taking the last 10%. And you want to blame the wolf for its demise?
That was my point. Modern man is without doubt has caused more change to the natural world in N. America. Not predators.
Mans changes have benefits some animals and hurt others. I can accept that.
Why do a few here want to eliminate yet another species from existence? Just cause this animal eats animals that you want to kill for your own benefit? There is a word for that. Selfish. Try to rationalize it any way you want, it all comes down to human greed. I can't accept that.
I have no problem managing by what ever means both prey and predator species. Skimming off some as long as the remainder is a healthy sustainable population. But I have an issue with those that want to eliminate predators so they have more to kill.
The dominant ecosystem (Oak Savanna) in my home state of WI is just about gone. Indians were a contributing factor in this ecosystem.
European man eliminated the essential ingredient (fire) for this ecosystem to exist. Now there are just remnants of it left here and there. These remnants are not big enough to support the large mammals that lived there, Elk and Bison. Other species are just hanging on. A good example is the Prairie Chicken. Not to mention the flora of this ecosystem.
I realize man and other factors have eliminated many species from this world. Some where not able to adapt to the changing environment and went out on their own. Some have gone out due to mans arrogance and greed. There is a difference.
