Dogs and thunderstorms. Frogs and rain. Elephants and earthquakes. These are some of the many observations, across cultures and the ages, of the acute ability of nonhuman animals to sense changes in the elements – of wind, water, earth and fire – often long before we do. They do this using senses many humans have lost in modern times, and some that we have never attained. While some may attribute these responses purely to the physical ability other animals have to see, taste, hear, smell or feel extremely subtle changes in the environment, it goes well beyond this. As people take the time to look and listen to what these animals sense, think and feel, our eyes are being opened to the extraordinary lives of the other species we share the planet with, both big and small.
