Economic vegetarianismAn economic vegetarian is a person who practices vegetarianism from either the philosophical viewpoint that the consumption of meat is expensive, part of a conscious simple living strategy or just because of necessity. In the developing world, where large numbers of poor people might not be averse to eating meat, they are regularly forced to not eat it, since meat can often be a luxury. Economic vegetarians believe that nutrition can be acquired more efficiently and at a lower price through vegetables, grains, etc.
Vegetarianism and religionThe practice of vegetarianism is strongly linked with a number of religious traditions worldwide. These include religions that originated in India, such as Hinduism, Jainism, Buddhism, and Sikhism. With close to 85% of India's billion-plus population practicing these religions, India remains the country with the highest number of vegetarians in the world. In Jainism, vegetarianism is mandatory for everyone; in Hinduism, Mahayana Buddhism and it is promoted by scriptures and religious authorities but not mandatory.
Environmental vegetarianismEnvironmental vegetarianism is the practice of vegetarianism that is motivated by the desire to create a sustainable diet, which avoids the negative environmental impact of meat production. Livestock as a whole is estimated to be responsible for around 15% of global greenhouse gas emissions. As a result, significant reduction in meat consumption has been advocated by, among others, the Intergovernmental Panel on Climate Change in their 2019 special report and as part of the 2017 World Scientists' Warning to Humanity.
Jewish vegetarianismJewish vegetarianism is a commitment to vegetarianism that is connected to Judaism, Jewish ethics or Jewish identity. Jewish vegetarians often cite Jewish principles regarding animal welfare, environmental ethics, moral character, and health as reasons for adopting a vegetarian or vegan diet. Vegetarianism was not traditionally a component of mainstream pre-modern Judaism, though the laws of kashrut limit consumption of certain animals or their products, with precise requirements for how animals are to be sacrificed and slaughtered (shechita).
Psychology of eating meatThe psychology of eating meat is a complex area of study illustrating the confluence of morality, emotions, cognition, and personality characteristics. Research into the psychological and cultural factors of meat-eating suggests correlations with masculinity, support for hierarchical values, and reduced openness to experience. Because meat eating is widely practiced but is sometimes associated with ambivalence, it has been used as a case study in moral psychology to illustrate theories of cognitive dissonance and moral disengagement.
Environmental impacts of animal agricultureThe environmental impacts of animal agriculture vary because of the wide variety of agricultural practices employed around the world. Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture.
Sustainable dietSustainable diets are "dietary patterns that promote all dimensions of individuals’ health and wellbeing; have low environmental pressure and impact; are accessible, affordable, safe and equitable; and are culturally acceptable". These diets are nutritious, eco-friendly, economically sustainable, and accessible to people of various socioeconomic backgrounds. Sustainable diets attempt to address nutrient deficiencies (e.g., undernourishment) and excesses (e.g.
Lacto-ovo vegetarianismLacto-ovo vegetarianism or ovo-lacto vegetarianism is a type of vegetarianism which forbids animal flesh but allows the consumption of animal products such as dairy and eggs. Unlike pescetarianism, it does not include fish or other seafood. A typical ovo-lacto vegetarian diet may include fruits, vegetables, grains, legumes, meat substitutes, nuts, seeds, soy, cheese, milk, yogurt and eggs. In India, such vegetarians are known as "eggetarian," which is a portmanteau of egg and vegetarian as "vegetarianism" usually refers to lacto vegetarianism in India.
Jain vegetarianismJain vegetarianism is practised by the followers of Jain culture and philosophy. It is one of the most rigorous forms of spiritually motivated diet on the Indian subcontinent and beyond. The Jain cuisine is completely lacto-vegetarian and also excludes root and underground vegetables such as potato, garlic, onion etc., to prevent injuring small insects and microorganisms; and also to prevent the entire plant getting uprooted and killed. It is practised by Jain ascetics and lay Jains.
CarnismCarnism is a concept used in discussions of humanity's relation to other animals, defined as a prevailing ideology in which people support the use and consumption of animal products, especially meat. Carnism is presented as a dominant belief system supported by a variety of defense mechanisms and mostly unchallenged assumptions. The term carnism was coined by social psychologist and author Melanie Joy in 2001 and popularized by her book Why We Love Dogs, Eat Pigs, and Wear Cows (2009).
