Abstract

This article discusses the use of nonhuman animals in three related aspects: 1) factual aspects about the treatment that we, humans, dispense to other animals, especially in meat and animal experimentation industries; 2) evaluative issues about the ethics of this treatment as we see in the ethical arguments pro (Singer; Regan) and contra (Naverson; Cohen); 3) some practical aspects about what we should to do. The ethical evaluation gives fundaments to the practical aspects that we conclude, with suggestions of actions, in particular the replacement of animal experimentation (inherently harmful) for investigation with nonhuman subjects of research (inherently non harmful, or therapeutic)
