Animal welfare

Animal welfare is the quality of life and overall well-being of animals. Formal standards of animal welfare vary between contexts, but are debated mostly by animal welfare groups, legislators, and academics. Animal welfare science uses measures such as longevity, disease, immunosuppression, behavior, physiology, and reproduction, although there is debate about which of these best indicate animal welfare.

Respect for animal welfare is often based on the belief that nonhuman animals are sentient and that consideration should be given to their well-being or suffering, especially when they are under the care of humans. These concerns can include how animals are slaughtered for food, how they are used in scientific research, how they are kept (as pets, in zoos, farms, circuses, etc.), and how human activities affect the welfare and survival of wild species.

There are two forms of criticism of the concept of animal welfare, coming from diametrically opposite positions. One view, held by some thinkers in history, holds that humans have no duties of any kind to animals. The other view is based on the animal rights position that animals should not be regarded as objects and any use of animals by humans is unacceptable. Accordingly, some animal rights proponents argue that the perception of better animal welfare is used as an excuse for continued exploitation of animals. Some authorities therefore treat animal welfare and animal rights as two opposing positions.^{[page needed]} Others see animal welfare gains as incremental steps towards animal rights.

The predominant view of modern neuroscientists, notwithstanding philosophical problems with the definition of consciousness even in humans, is that consciousness exists in nonhuman animals; however, some still maintain that consciousness is a philosophical question that may never be scientifically resolved. A new study has devised a unique way to dissociate conscious from nonconscious perception in animals. The researchers built experiments predicting opposite behavioral outcomes to consciously vs. non-consciously perceived stimuli. The monkeys' behaviors displayed these exact opposite signatures, just like aware and unaware humans tested in the study.

Animal protection laws were enacted as early as the 1st millennium BCE in India. Several Indian kings built hospitals for animals, and emperor Ashoka (304–232 BCE) issued orders against hunting and animal slaughter, in line with ahimsa, the doctrine of non-violence. In the 13th century CE, Genghis Khan protected wildlife in Mongolia during the breeding season (March to October).

Early legislation in the Western world on behalf of animals includes the Ireland Parliament (Thomas Wentworth) "An Act against Plowing by the Tayle, and pulling the Wooll off living Sheep", 1635, and the Massachusetts Colony (Nathaniel Ward) "Off the Bruite Creatures" Liberty 92 and 93 in the "Massachusetts Body of Liberties" of 1641. In the Edo period of Japan, Tokugawa Tsunayoshi (1646 - 1709) instituted several laws relating to animal welfare, particularly towards dogs, earning him the nickname of "the dog Shogun".

In 1776, English clergyman Humphrey Primatt authored A Dissertation on the Duty of Mercy and Sin of Cruelty to Brute Animals, one of the first books published in support of animal welfare. Marc Bekoff said that "Primatt was largely responsible for bringing animal welfare to the attention of the general public."

Since 1822, when Irish MP Richard Martin brought the "Cruel Treatment of Cattle Act 1822" through Parliament offering protection from cruelty to cattle, horses, and sheep, an animal welfare movement has been active in England. Martin was among the founders of the world's first animal welfare organization, the Society for the Prevention of Cruelty to Animals, or SPCA, in 1824. In 1840, Queen Victoria gave the society her blessing, and it became the RSPCA. The society used members' donations to employ a growing network of inspectors, whose job was to identify abusers, gather evidence, and report them to the authorities.
