It is true, Wolves are hunters. More than that, they are incredibly successful hunters. They work as a team, have incredible endurance and a very high level of intelligence. This is perhaps why in the last few centuries their numbers have been greatly depleted.
In places like western Europe and the USA, they were close to extinction as a whole and had become locally extinct in much of their range. So is this fear mongering reasonable? Of course not.
Here she is talking about wolves in Colorado. She quoted figures of 500 attacks from 2002- the present, and stated that 30 people died in this time – scary numbers indeed. However, she was instantly fact-checked – those were the number of attacks around the world not just in the USA, only 1 death occurred there.
Of course, every death is sad, but to put it in perspective, each year 175-200 people die as a result of their car colliding with a deer. So over the same period, there were 3500-4000 car deaths as a result of deer – and wolf presence greatly reduces this, both by reducing the deer numbers, and creating a climate of fear, which makes deer stay away from open spaces, and so cross roads far less often.
