Yeah predators share a direct relationship with the populations of their prey. And they are very beneficial to their populations.

I'm also a hunter (though I mostly hunt for food and very rarely for sport), but I don't let my involvement with that cloud my judgment... Obviously you didn't watch the video because you still don't understand how apex predators (in general) are very important to the ecosystem (the natural process of how the earth works). Something that people need to understand is that wolves have been here (in North America) thousands of years longer then humans have, and until humans (mostly Europeans) the population of the deer and buffalo grew to insanely large numbers (even with tens of thousands of wolves). You can't (in good moral conscience) kill off a predator just because we (humans) have drastically reduced the population of their food and want to have solo hunting rights to hunt (in excess and in sport) what's left. [spoiler]Keep in mind that wolves only kill what they need, nothing more. Also they generally only kill the week, sick, or injured thus leaving the population of whatever animal that are hunting stronger.[/spoiler] They have just as much right to live and hunt here as you or I do. ... .. -Prince of Wolves
