It’s a dog eat dog world out there, literally and figurative. Humans have drawn much from the animal kingdom: Metaphors and idiomatic expressions to grace our languages, food and clothing for survival, and their mere presence to delight our vision and feed our superiority complex. But make no mistake, animals can be deadly and at times have unleashed their revenge on us to punish our hubris. If the animal kingdom were to exact revenge on human beings, we’d be dropping like flies. All animals have the potential to kill but do so in self-defence or when they feel threatened. Only one animal kills for sport.
