Meat in the context of Selective breeding

Human cannibalism is the act or practice of humans eating the flesh or internal organs of other human beings. A person who practices cannibalism is called a cannibal. The meaning of "cannibalism" has been extended into zoology to describe animals consuming parts of individuals of the same species as food.

Anatomically modern humans, Neanderthals, and Homo antecessor are known to have practised cannibalism to some extent in the Pleistocene. Cannibalism was occasionally practised in Egypt during ancient and Roman times, as well as later during severe famines. The Island Caribs of the Lesser Antilles, whose name is the origin of the word cannibal, acquired a long-standing reputation as eaters of human flesh, reconfirmed when their legends were recorded in the 17th century. Some controversy exists over the accuracy of these legends and the prevalence of actual cannibalism in the culture.

Lamb and mutton, collectively sheep meat (or sheepmeat) is one of the most common meats around the world, taken meat from the domestic sheep, Ovis aries, and generally divided into lamb, from sheep in their first year, hogget, from sheep in their second, and mutton, from older sheep.

In South Asian and Caribbean cuisine, "mutton" often means goat meat. At various times and places, "mutton" or "goat mutton" has occasionally been used to mean goat meat.

Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, management, production, nutrition, selective breeding, and the raising of livestock. Husbandry has a long history, starting with the Neolithic Revolution when animals were first domesticated, from around 13,000 BC onwards, predating farming of the first crops. During the period of ancient societies like ancient Egypt, cattle, sheep, goats, and pigs were being raised on farms.

Major changes took place in the Columbian exchange, when Old World livestock were brought to the New World, and then in the British Agricultural Revolution of the 18th century, when livestock breeds like the Dishley Longhorn cattle and Lincoln Longwool sheep were rapidly improved by agriculturalists, such as Robert Bakewell, to yield more meat, milk, and wool. A wide range of other species, such as horse, water buffalo, llama, rabbit, and guinea pig, are used as livestock in some parts of the world. Insect farming, as well as aquaculture of fish, molluscs, and crustaceans, is widespread.

Sushi (すし, 寿司, 鮨, 鮓; pronounced [sɯɕiꜜ] or [sɯꜜɕi] ) is a traditional Japanese dish made with vinegared rice (鮨飯, sushi-meshi), typically seasoned with sugar and salt, and combined with a variety of ingredients (ねた, neta), such as seafood, vegetables, or meat; raw seafood is the most common, although some may be cooked. While sushi has numerous styles and presentations, the current defining component is the vinegared rice, also known as shari (しゃり), or sumeshi (酢飯).

The modern form of sushi is believed to have been created by Hanaya Yohei, who invented nigiri-zushi, the most commonly recognized type today, in which seafood is placed on hand-pressed, vinegared rice. This innovation occurred around 1824 in the Edo period (1603–1867). It was the fast food of the chōnin class in the Edo period.

Hunting is the human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases (see varminting), for trade/tourism (see safari), or for ecological conservation against overpopulation and invasive species (commonly called a cull).

Recreationally hunted species are generally referred to as the game, and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; and an experienced hunter who helps organise a hunt and/or manage the game reserve is also known as a gamekeeper.

Domestication is a multi-generational mutualistic relationship in which an animal species, such as humans or leafcutter ants, takes over control and care of another species, such as sheep or fungi, to obtain from them a steady supply of resources, such as meat, milk, or labor. The process is gradual and geographically diffuse, based on trial and error. Domestication affected genes for behavior in animals, making them less aggressive. In plants, domestication affected genes for morphology, such as increasing seed size and stopping the shattering of cereal seedheads. Such changes both make domesticated organisms easier to handle and reduce their ability to survive in the wild.

The first animal to be domesticated by humans was the dog, as a commensal, at least 15,000 years ago. Other animals, including goats, sheep, and cows, were domesticated around 11,000 years ago. Among birds, the chicken was first domesticated in East Asia, seemingly for cockfighting, some 7,000 years ago. The horse came under domestication around 5,500 years ago in central Asia as a working animal. Among invertebrates, the silkworm and the western honey bee were domesticated over 5,000 years ago for silk and honey, respectively.

Livestock are the domesticated animals that are raised in an agricultural setting to provide labor and produce diversified animal products for human consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals which are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, and goats. Livestock production are mainly a source for farm work and human consumption.

The breeding, maintenance, slaughter and general subjugation of livestock called animal husbandry, is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and periods. It continues to play a major economic and cultural role in numerous communities.

Industrial agriculture is a form of modern farming that refers to the industrialized production of crops and animals and animal products like eggs or milk. The methods of industrial agriculture include innovation in agricultural machinery and farming methods, genetic technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, the application of patent protection to genetic information, and global trade. These methods are widespread in developed nations and increasingly prevalent worldwide. Most of the meat, dairy, eggs, fruits and vegetables available in supermarkets are produced in this way.

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.

A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather.

The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants.

Game or quarry are wild animals which are hunted for animal products (primarily meat), for recreation ("sporting"), or for trophies. The species of animals hunted as game varies in different parts of the world and by different local jurisdictions, though most are terrestrial mammals and birds. Fish caught non-commercially (recreational fishing) are also referred to as game fish.

Poultry (/ˈpoʊltri/) are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys). The term also includes waterfowls of the family Anatidae (ducks and geese) but does not include wild birds hunted for food known as game or quarry.

Recent genomic studies involving the four extant junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia. This was previously believed to have occurred around 5,400 years ago, also in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds from eggs collected from the wild, but later involved keeping the birds permanently in captivity. Domesticated chickens may have been used for cockfighting at first and quail kept for their songs, but people soon realised the advantages of having a captive-bred source of food. Selective breeding for fast growth, egg-laying ability, conformation, plumage and docility took place over the centuries, and modern breeds often look very different from their wild ancestors. Although some birds are still kept in small flocks in extensive systems, most birds available in the market today are reared in intensive commercial enterprises.

Pork is the culinary name for the meat of the pig (Sus domesticus). It is the second most commonly consumed type of meat worldwide, following poultry, with evidence of pig husbandry dating back to 8000–9000 BCE.

Pork is eaten both freshly cooked and preserved; curing extends the shelf life of pork products. Ham, gammon, bacon, and pork sausage are examples of preserved pork. Charcuterie is the branch of cooking devoted to prepared meat products, many from pork.

In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products. Grazing is often done on lands that are unsuitable for arable farming, although there are occasions where arable lands and even prior farmlands are intentionally kept or converted to pastures to raise commercially valuable grazing animals.

Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site.

Intensive animal farming, industrial livestock production, and macro-farms, also known as factory farming, is a type of intensive agriculture used by the meat and dairy industry to maximize animal production while minimizing costs. To achieve this, agribusinesses keep livestock such as cattle, poultry, and fish at high stocking densities, at large scale, and using modern machinery, biotechnology, and pharmaceutics. The main products are meat, milk and eggs for human consumption.

While intensive animal farming can produce large amounts of animal products at a low cost with reduced human labor, it is controversial as it raises several ethical concerns, including animal welfare issues (confinement, mutilations, stress-induced aggression, breeding complications), harm to the environment and wildlife (greenhouse gases, deforestation, eutrophication), increased use of cropland to produce animal feed, public health risks (zoonotic diseases, pandemic risks, antibiotic resistance), and worker exploitation, particularly of undocumented workers. The animal agriculture industry has been accused of actively supporting disinformation campaigns and preventing policies to address climate change.
