Human beings may not stand to win in a fair fight against most of these species, but thanks to our ingenuity, we have learned how to arm ourselves with weapons and tools which have placed us at the top of the food chain (at least for the time being). We also get extra points on the deadly scale for our aggression, not only toward other animals, but toward each other. The scale to which we take our destruction is unique. No other animal starts worldwide wars or blasts whole regions of the earth into total ruin with nuclear weapons. Without a doubt, the most dangerous animal in the world is the face you see in the mirror each day.
