I'm aware of the increase in wolf problems out west. I believe they should be regulated to avoid bigger livestock and possibly human encounters. Sell only so many tags to keep them in check. Now in no way is this going to threaten there overall numbers making them extinct, but it will keep them from getting out of control. Its good to have them around for their balance on wildlife, but should not be protected forever judging on how their numbers have grown already since reintroduction. They would just become out of control.
