Mainstream views from institutions emphasize veganism's role in reducing animal suffering and exploitation, aligning with growing societal concerns about factory farming practices. Experts argue it represents a compassionate choice that avoids contributing to the estimated billions of animals raised and slaughtered annually for food. This perspective is supported by ethical frameworks in philosophy and animal rights discussions, promoting a shift toward plant-based alternatives that respect sentience.

Environmental Sustainability
Reputable sources highlight veganism's potential to lower greenhouse gas emissions, reduce water usage, and decrease deforestation associated with livestock agriculture. Mainstream environmental organizations note that animal agriculture accounts for a significant portion of global emissions, making plant-based diets a key strategy for mitigating climate change. Balanced analyses show that widespread adoption could lead to more sustainable food systems without compromising nutritional needs when properly planned.
Health and Nutritional Benefits
Health authorities often cite that well-planned vegan diets can lower risks of heart disease, type 2 diabetes, and certain cancers due to higher intake of fiber, antioxidants, and lower saturated fats. While requiring attention to nutrients like B12 and iron, mainstream medical consensus supports its viability for all life stages with guidance, as per dietary guidelines from major bodies.

Conclusion
Overall, the mainstream perspective regards veganism as a positive, ethical, and sustainable lifestyle choice with notable benefits, provided it is approached thoughtfully.
Alternative Views
Regenerative omnivory: well-managed livestock heal land
This view holds that animals are part of healthy ecosystems. Grazing herds can build soil carbon, restore grasslands and use land that is unsuitable for crops. Supporters say vegan farming often depends on monocrop tillage, pesticides and habitat loss, which kill many field animals. They argue that the real problem is industrial feedlots, not animal agriculture as such. They also say that a world with no grazing would lose both biodiversity and rural livelihoods. Critics of this view dispute the net carbon claims, but its proponents cite holistic planned grazing and pasture-based case studies.

Nutritional skepticism: animal foods are optimal for human health
Proponents argue that humans evolved eating animal foods, and that meat, fish, eggs and organ meats supply B12, heme iron, zinc, retinol, creatine, taurine, DHA and complete proteins in highly bioavailable forms. They say vegan diets need supplements and fortified foods to avoid deficiencies. They also worry about children, pregnant women and people with certain health conditions. Some carnivore-diet advocates go further and claim that eliminating plant foods helps with autoimmune and metabolic problems, though this rests mostly on anecdotes and small surveys. Their strongest argument is that diets should be judged on nutrient density and individual response, not on ideology.

Animal rights without veganism: welfarism and 'humane' reform
Some ethicists agree that animal suffering matters, but they doubt that total abstention is the best strategy or even morally required. They argue that high-welfare farming, cage-free laws and reduced consumption can spare more animals, because far more people will take part. Strict veganism, in their view, can alienate people and make a movement seem elitist. Others hold that humane use of animals is ethically defensible. Peter Singer's utilitarian approach supports shifting the focus to reducing suffering and does not insist on purity. Critics such as Gary Francione hold the opposite position and call welfarism ineffective.

Vegan critique from within: 'new welfarism' and technology as the real solution
Some advocates argue that individual veganism will never reach more than a small share of the population, so systemic change matters more. They back plant-based meat, precision fermentation and cultivated meat, or policy changes such as subsidy reform and a higher price for meat. They argue that consumer purity is less effective than changing the food system. Critics in this camp say that guilt-based messaging has stalled, as plant-based meat sales have flattened in recent years.

Indigenous and food-sovereignty critique
This perspective says that universalist veganism ignores cultures whose food, ecology and identity rely on hunting, fishing, herding or animal husbandry, such as Arctic, pastoralist and Plains communities. Where crops are impractical, it argues, animal foods are the sustainable choice. It also criticizes Western vegan campaigns as a form of cultural imperialism.
Attributed to: Indigenous food-sovereignty writers such as Sean Sherman (The Sioux Chef) and Kim TallBear have raised related critiques of colonial food norms. I'm unsure who explicitly holds the full position as stated, so I'm not attributing it more specifically.
