Speciesism is a term used in philosophy regarding the treatment of individuals of different species. The term has several different definitions. Some specifically define speciesism as discrimination or unjustified treatment based on an individual's species membership, while others define it as differential treatment without regard to whether the treatment is justified or not. Richard D. Ryder, who coined the term, defined it as "a prejudice or attitude of bias in favour of the interests of members of one's own species and against those of members of other species". Speciesism results in the belief that humans have the right to use non-human animals in exploitative ways which is pervasive in the modern society. Studies from 2015 and 2019 suggest that people who support animal exploitation also tend to have intersectional bias that encapsulates and endorses racist, sexist, and other prejudicial views, which furthers the beliefs in human supremacy and group dominance to justify systems of inequality and oppression.
