This video is about animal empathy (anthropomorphism) and our struggles with mortality. The title reflects a pun, with two supporting sources. The first, that we often transfer our most profound emotions onto other animals, i.e., "one species removed." The second, the crackpot but very moving theories of Rudolf Steiner. He believed that animals have a group soul, used interchangeably with the term "species." When one animal dies, the group replaces that part of itself. By contrast, each human being is an individual species/soul, so that when we die, a whole species is rendered extinct.
