All current versions of ethics for human interaction with animals are based on theories originally developed for relationships between humans or for human understanding of the environment. The perceived analogies between relationships among humans those theories were designed for and the relationships between human and animals have led to specifically revised and adapted theories for ethical interaction between humans and animals. In this essay I propose two further analogies that I develop into one core argument to cover specific issues in (...) human–animal relationships not yet adequately addressed. First I adapt the ethical theory designed for use between human professionals and their clients for analogous use in the power relationship between humans and animals; second I similarly adapt the ethical theory designed for interactions between humans and the global environment. I use elephants as example of an animal species and they stand as proxy for all similar animal species. The overall argument justifies moral duties for humanity to protect both species and the global biosphere as home for all living organisms. (shrink)
