Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics.
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.

Conversations regarding the ethics of eating meat are focused on whether or not it is moral to eat non-human animals. Ultimately, this is a debate that has been ongoing for millennia, and it remains one of the most prominent topics in food ethics. Individuals who promote meat consumption do so for a number of reasons, such as health, cultural traditions, religious beliefs, and scientific arguments that support the practice. Those who support meat consumption typically argue that making a meat-free diet mandatory would be wrong because it fails to consider the individual nutritional needs of humans at various stages of life, fails to account for biological differences between the sexes, ignores the reality of human evolution, ignores various cultural considerations, or because it would limit the adaptability of the human species.
Christian ethics, also known as moral theology, is a multi-faceted ethical system. It is a virtue ethic, which focuses on building moral character, and a deontological ethic which emphasizes duty. It also incorporates natural law ethics, which is built on the belief that it is the very nature of humans – created in the image of God and capable of morality, cooperation, rationality, discernment and so on – that informs how life should be lived, and that awareness of sin does not require special revelation. Other aspects of Christian ethics, represented by movements such as the social Gospel and liberation theology, may be combined into a fourth area sometimes called prophetic ethics.
Animal rights is the philosophy according to which many or all sentient animals have moral worth independent of their utility to humans, and that their most basic interests—such as avoiding suffering—should be afforded the same consideration as similar interests of human beings. Broadly speaking, and particularly in popular discourse, the term "animal rights" is often used synonymously with "animal protection" or "animal liberation". More narrowly, "animal rights" refers to the idea that many animals have fundamental rights to be treated with respect as individuals—rights to life, liberty, and freedom from torture that may not be overridden by considerations of aggregate welfare.

Gary Edward Varner was an American philosopher specializing in environmental ethics, philosophical questions related to animal rights and animal welfare, and R. M. Hare's two-level utilitarianism. At the time of his death, he was an emeritus professor in the department of philosophy at Texas A&M University; he had been based at the university since 1990. He was educated at Arizona State University, the University of Georgia, and the University of Wisconsin–Madison; at Madison, where he was supervised by Jon Morline, he wrote one of the first doctoral theses on environmental ethics. Varner's first monograph was In Nature's Interests?, which was published by Oxford University Press in 1998. In the book, Varner defended a form of biocentric individualism, according to which all living entities have morally considerable interests.
The Universal Kinship is a 1906 book by American zoologist and philosopher J. Howard Moore. In the book, Moore advocates for the doctrine of Universal Kinship, a secular sentiocentric philosophy, which mandates the ethical consideration and treatment of all sentient beings based on Darwinian principles of shared evolutionary kinship, and a universal application of the Golden Rule, a challenge to existing anthropocentric hierarchies and ethics. The book built on arguments Moore first made in Better-World Philosophy, published in 1899, and was followed by The New Ethics in 1907. The Universal Kinship was endorsed by a number of contemporary figures including Henry S. Salt, Mark Twain and Jack London, Eugene V. Debs and Mona Caird.
