Yeah, it's that whole 'dynamic balance of sustainable numbers' thing.  The way it's SUPPOSED to work is that assemblages of predators and prey evolve together over thousands, sometimes millions, of years, struggling to eat and not be eaten, to where prey species don't become so numerous they exhaust their food supply and then starve, and predators don't become so numerous they eat all the prey and then starve. 

We see that here with the cyclical increase/decrease of snowshoe hares, closely followed by that of lynx.  Not much room--or reason--in such biological processes for 'trophies'.  Someone should perhaps try to explain that in little words to O'bonobo.  And to the Alaska Board of Game.
