Speciesism: The Movie (2013)

Speciesism, or the belief in species superiority, is a term known since 1970. In this film, well-known animal rights activists and advocates, Steven Best and Peter Singer, explain why it is irrational and morally wrong to consider sentient beings as mere things or property. They were among the most significant opponents of the ideology and methods of speciesism, contributing to the development of the philosophical framework and civil initiatives against speciesism.
