About this "kill only what they need" - that drivel was also presented here by the 'antis'. Turned out they found an unemployed 'graduate of biology' (same schooling as both of my girls - BSC's) whom they paid to back their statements in a news paper and in interviews. Of course, it's crap, but that's the kind of thing we're dealing with or against.
Kill only the weak or wounded is another 'statement' used, saying it improves the herd - ie; elk or caribou. Bulltwitty - yes, anything previously wounded is now weak or wounded, and is easly brought donw but the herd bull - the prime genetics of the herd stands back and alone to protect his herd and is the first to go. That's natural selection at it's worse. Thus, the herd's genetics gets poorer and poorer for a period of time. It takes a young spike who becomes a monarch, who can reverse this - again, time. With man's cattle to support the wolves, the herd suffers in times of draught, severe winters and even more to predation due to downgrading genetics.

The problem goes far beyond them killing a few too many ungulates.

We are here to stay and to live the way be demand, we cannot have a healthy population of such mobile and deadly predetors.
