You go into wildlife areas, you risk being attacked by wildlife. It's a fact of life and is actually pretty darn rare. Go in to the ocean, a shark could get you.
Life is not risk free and in these cases people are going into the animal's territory most of the time. There are cases where animals actually enter urban/sburban areas, but not often.
A person I know lives on a remote ranch. "Pets" disappear pretty often, if left outside. Large birds of prey will just snarf up the little kitty cat. Wolves or coyotes will certainly kill bigger pets, as well as the samll ones.
Which animal is the most deadly to humans? Other humans, intentionally or not. By a huge margin. I'm regularly scared out of my wits commuting on highway 99.
