It's a simple problem, Bobert. Prolific herbivores + insuficient predators = problem. Much the same with moose in the NE and gators in FL. Perhaps a mechanism to gain attention and get a response to the problem would be for folks who are in some way damaged by the abundance of critters (damaged cars; gobbled gardens (in the American sense of the term); damaged landscape foliage, pets eaten, kids killed or maimed (sadly, its true), etc., etc.) should start to invoice their respective state legislatures and legislators for recompense. Civil suit is another option on more egregious cases.
