In the UK there is precisely one deadly animal. It's a snake that, likewise, will fucking flee at the sight of any human. We're basically immune to everything because there's nothing there to hurt us. Even the probable reintroduction of wolves to some parts of Scotland don't matter because wolves only look scary but don't actually give a shit unless it's been a bad winter and you're caught alone, which you won't be because you have a car and don't need to sleep halfway up a tree in December.
