Environmental vegetarianism in the context of "Vegetarianism"

Conversations regarding the ethics of eating meat are focused on whether or not it is moral to eat non-human animals. People who abstain from eating meat are generally known as "vegetarians" and people who avoid all animal by-products are known as “vegans”. They avoid meat for a variety of reasons, including taste preference, animal welfare, ethical reasons, religion, the environmental impact of meat production (environmental vegetarianism), health considerations, and antimicrobial resistance. 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. The majority of the world’s health and dietetics associations state that a well-planned vegetarian or vegan diet can be nutritionally adequate for all stages of life.

A common argument used in the animal rights movement is the argument from marginal cases, asserting that non-human animals should have the moral status similar to that of marginal case human beings such as human infants, the senile, the comatose, and the cognitively disabled. Proponents argue that there are no morally relevant traits that these marginal humans possess that animals lack.

Vegetarianism is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, freshwater fish, insects, and the flesh of any other animal). It may also include abstaining from eating all by-products of animal slaughter. A person who practices vegetarianism is known as a vegetarian.

Vegetarianism may be adopted for various reasons. Many people object to eating meat out of respect for sentient animal life. Such ethical motivations have been codified under various religious beliefs as well as animal rights advocacy. Other motivations for vegetarianism are health-related, political, environmental, cultural, aesthetic, economic, taste-related, or relate to other personal preferences.
