The only thing we can do is get them de-listed. IMHO large predators such as Wolves, cougar & bears are a "bunny huggers" best friend. Anti-hunter know they can use large predators as a tool to end hunting as we know it.
I won't tell you to shoot a wolf in the guts so it will run off & die. A pack of woves will not allow a member of there pack to be weak or sick. If one becomes weak or sick they kill it. If a wolf is killed by another wolf, no law has been broken, it just mother nature taking its course.
