Veganism. The debate.

Veganism: Books, Papers, Articles, and Op-Eds

This list brings together ethical arguments, investigative accounts, nutrition and environmental research, and informed critiques. Books and opinion pieces make arguments; empirical papers answer narrower research questions and also have assumptions and limitations. Use the notes below to distinguish evidence from advocacy.

Suggested starting sequence: Peter Singer’s Animal Liberation Now for an influential utilitarian argument; Poore and Nemecek (2018) for a comparative environmental assessment; the Academy of Nutrition and Dietetics’ 2025 paper for its current adult-focused position on vegetarian and vegan dietary patterns; and White and Hall (2017), read alongside published critiques, for a contested model of removing animals from US agriculture. For opposing and qualified views, read Pollan, Niman, and Fairlie, and see the Monbiot entry, since his position has changed more than once.

Philosophy and ethics
  • Peter Singer, Animal Liberation Now: The Definitive Classic Renewed (2023). A substantially updated edition of Singer’s 1975 Animal Liberation, an influential work in the modern animal-rights movement. Singer’s argument is utilitarian, focused on taking sentient animals’ interests seriously.
  • Tom Regan, The Case for Animal Rights (1983). A rights-based argument often contrasted with Singer’s utilitarian approach.
  • Gary L. Francione, Animals as Persons: Essays on the Abolition of Animal Exploitation (2008). Develops Francione’s abolitionist view that animals should not be treated as property and that veganism is a baseline implication of that view. This is an account of Francione’s position, not a neutral consensus statement.
  • Peter Singer and Jim Mason, The Ethics of What We Eat: Why Our Food Choices Matter (2006; the original US edition was titled The Way We Eat). Uses the food choices of three American families to examine the ethical consequences of eating.
  • Carol J. Adams, The Sexual Politics of Meat: A Feminist-Vegetarian Critical Theory (1990; later editions available). A feminist analysis of the cultural links among meat, gender, and power.
  • Melanie Joy, Why We Love Dogs, Eat Pigs, and Wear Cows: An Introduction to Carnism (2010 edition). Introduces Joy’s account of the beliefs and social practices that normalize eating some animals but not others. Check the edition when citing; publication records may reflect different editions.
  • Aph and Syl Ko, Aphro-ism: Essays on Pop Culture, Feminism, and Black Veganism from Two Sisters (2017). Adds Black vegan thought and intersectional critiques of race, animality, and oppression, perspectives otherwise underrepresented here.
  • Cora Diamond, “Eating Meat and Eating People,” Philosophy, 53(206), 465–479 (1978). A philosophical challenge to standard animal-rights arguments, not a straightforward defense of meat eating.
  • Jeff McMahan, “Eating Animals the Nice Way,” Daedalus, 137(1), 66–76 (2008). Examines whether raising and killing animals under comparatively good conditions could make eating them permissible.

Arguments for moderation or against vegan conclusions
  • Michael Pollan, “An Animal’s Place,” The New York Times Magazine (November 10, 2002). Argues for a conscientious form of animal eating, while condemning industrial practices and calling for greater awareness and respect.
  • George Monbiot, “Why Vegans Were Right All Along” (2002); “I Was Wrong About Veganism. Let Them Eat Meat—but Farm It Properly” (2010); and Regenesis: Feeding the World Without Devouring the Planet (2022). Monbiot’s position has changed more than once, so the 2010 column should not be read as his current view. The 2002 piece made an environmental and social-justice case for veganism, and the 2010 piece qualified it, arguing that the real problem was how animals are farmed. In Regenesis, he argues against almost all livestock farming, including supposedly benign pasture-fed systems, mainly on land-use grounds, and looks to alternatives such as precision fermentation. Reviewers describe him as vegan or largely vegan; no recent statement from him on his own diet was found. Critics, including the Sustainable Food Trust, argue that his focus on yield per hectare undervalues extensive grazing. He and Simon Fairlie have debated these questions publicly.
  • Nicolette Hahn Niman, “The Carnivore’s Dilemma,” The New York Times (October 31, 2009). Makes a case for well-managed livestock within sustainable agriculture. Treat its environmental claims as an argument to compare with lifecycle analyses, not as settled findings.
  • Nina Planck, “Death by Veganism,” The New York Times (May 21, 2007). An opinion piece criticizing vegan diets for infants. It discusses a case in which an infant was reportedly fed soy milk and apple juice—not a properly planned vegan diet or commercial infant formula—so the case does not establish that vegan diets generally cause infant deaths.
  • Simon Fairlie, Meat: A Benign Extravagance (2010). Argues for a smaller mixed farming system that uses grazing land and food byproducts to support some livestock production. It offers a substantial challenge to simplified comparisons between all animal and plant agriculture.
Reading the evidence carefully
  • Poore and Nemecek and White and Hall do not directly contradict one another. Poore and Nemecek compare environmental footprints across products and producers; White and Hall model a particular scenario for removing animals from US agriculture, with a different question and assumptions.
  • Impacts vary with the food, production system, location, environmental measure, and model. A claim about one metric—such as greenhouse gases—does not settle other questions, including land use, biodiversity, nutrition, or animal welfare.
  • Cohort studies such as Tong et al. identify associations, not proof that a diet caused an outcome. Model-based studies such as Springmann et al. and White and Hall estimate outcomes under stated assumptions; their conclusions are only as applicable as those assumptions.
  • The 2025 Academy position paper is limited to adults. Its existence should not be used to make claims about children or pregnancy; the older 2016 position is expired.
  • Veganism is a broad ethical and practical commitment; a vegan diet is one part of it. Nutrition research can inform dietary planning, but it does not answer the ethical argument by itself.
