The Eid al-Adha is major annual festival of animal sacrifice in Islam. In Indonesia alone, for example, some 800,000 animals were sacrificed in 2014 by its Muslims on the festival, but the number can be a bit lower or higher depending on the economic conditions.[https://blogs.wsj.com/briefly/2015/09/23/indoeid0923/ Animal Sacrifice in the World’s Largest Muslim-Majority Nation], The Wall Street Journal (September 23, 2015) According to Lesley Hazleton, in Turkey about 2,500,000 sheep, cows and goats are sacrificed each year to observe the Islamic festival of animal sacrifice, with a part of the sacrificed animal given to the needy who didn't sacrifice an animal.{{cite book|author=Lesley Hazleton|title=Mary |url=https://books.google.com/books?id=P8KE91p-NLcC&pg=PA41|year=2008|publisher=Bloomsbury Publishing|isbn=978-1-59691-799-6|page=41}} According to The Independent, nearly 10,000,000 animals are sacrificed in Pakistan every year on Eid.[https://www.independent.co.uk/news/uk/home-news/eid-al-adha-when-why-does-not-fall-same-date-every-year-hajj-islam-muslims-saudi-arabia-a7228801.html Eid al-Adha 2016: When is it and why does it not fall on the same date every year?], Harriet Agerholm, The Independent (6 September 2016){{cite journal | last1=Zaidi | first1=Farrah | last2=Chen | first2=Xue-xin | title=A preliminary survey of carrion breeding insects associated with the Eid ul Azha festival in remote Pakistan | journal=Forensic Science International | publisher=Elsevier BV | volume=209 | issue=1–3 | year=2011 | doi=10.1016/j.forsciint.2011.01.027 | pages=186–194| pmid=21330071 }} Millions of animal are brought into the Middle East from north Africa and parts of Asia and slaughter every year on Eid al-Adha.{{cite journal | last=Brooke | first=Clarke | title=Sacred Slaughter: The Sacrificing of Animals at theHajjandId al-Adha | journal=Journal of Cultural Geography | publisher=Taylor & Francis | volume=7 | issue=2 | year=1987 | doi=10.1080/08873638709478508 | pages=67–88}}

Animal slaughter is the killing of nonhuman animals, and often refers to the slaughter of livestock. Animals may be slaughtered for humans to obtain food, and also if they are diseased and unable to be consumed as food.

{{main|Halal}}

Halāl ({{langx|ar|حلال}} {{transl|ar|ALA|ḥalāl}}, 'permissible'), also spelled "hallal" or "halaal", is any object or an action which is permissible to use or engage in, according to Islamic law. The term covers and designates not only food and drink but also all matters of daily life.Quran 7:157 There are three ways of halal killing: slitting of the throat (dabh), plunging the knife into the dimple over the breast bone (nahr), and killing in some other way ('aqr). The name of God (bismillah) must be said before killing the animal. The killing must be swift and with no prior stunning of the animal being killed.{{cite journal|last=Benkheira|first=Mohammed|title=Artificial death, canonical death: Ritual slaughter in Islam.|journal=Food and Foodways|date=2000|volume=8|series=4|issue=4|pages=227–252|url=http://journals2.scholarsportal.info/pdf/07409710/v08i0004/227_adcdrsii.xml|doi=10.1080/07409710.2000.9962092|s2cid=143164349}} Blood must be drained out of the carcass.{{cite web|last1=Jones|first1=Sam|date=March 6, 2014|title=Halal, shechita and the politics of animal slaughter|url=https://www.theguardian.com/world/2014/mar/06/halal-shechita-politics-animal-slaughter|website=The Guardian|access-date=February 2, 2016}}

{{main|Kashrut}}

Kashrut (also kashruth or kashrus, {{Script/Hebrew|כַּשְׁרוּת}}) is the set of Jewish religious dietary laws. Food that may be consumed according to halakha (Jewish law) is termed kosher {{IPAc-en|'|k|oʊ|ʃ|ər}} in English, from the Ashkenazi pronunciation of the Hebrew term kashér ({{Script/Hebrew|כָּשֵׁר}}), meaning "fit" (in this context, fit for consumption). Shechita is the process of slaughtering prescribed by Jewish dietary laws.

{{main|Qurban}}

Qurbān usually denotes the sacrifice of a livestock animal during Eid al-Adha, a Muslim holiday.

{{main|Shechita}}

In Shechita the killing must be performed by a shochet ({{langx|he|שוחט}}). The process involves severing the trachea, esophagus, carotid arteries, jugular veins and vagus nerve swiftly with a special knife which is extremely sharp. This is done with the intention of causing a rapid drop in blood pressure in the brain and loss of consciousness, to reduce the pain felt by the animal and exsanguinate it at the same time.[http://www.chabad.org/library/article_cdo/aid/222240/jewish/What-is-Shechita.htm What is Shechita?] chabad.org{{Cite web |url=http://www.shechitauk.org/fileadmin/user_upload/pdf/Physiological_insights_into_Shechita__S.D.Rosen__Veterinary_Record_2004.pdf |title=S.

In North America, animals such as bear, wolf, caribou, moose, elk, boar, sheep and bison are hunted. In South America, deer and other species are hunted. In Europe, sheep, boar, goats, elk, deer, and other species are hunted. In Asia, several species of deer, bear, sheep and other species are hunted. In Australia, several species of deer and wild boar are hunted.

{{main|Big-game hunting}}

Big-game hunting is the hunting of large game, almost always large terrestrial mammals, for meat, other animal by-products (such as horn or bone), trophy or sport. The term is historically associated with the hunting of Africa's "big five" game (lion, African elephant, Cape buffalo, leopard and rhinoceros), and with tigers and rhinoceroses on the Indian subcontinent. Along with the big five animals, many other species are hunted including but not limited to kudu, antelope, and hartebeest. Moose, elk, bear, mountain lion, caribou, bison and deer are the largest game hunted in North America, which is where most big-game hunting is conducted today.

Big-game hunting is conducted in Africa, North America, South America, Europe, Asia and Australia. In Africa, lion, Cape buffalo, elephant, giraffe and other large game animals are hunted.

{{main|Roadkill}}

Animals are often killed by moving vehicles. This is known as roadkill. In one case in North Carolina in early 2016 a deer was road killed and butchered outside a restaurant. A concerned citizen took cell phone images and called the police. The restaurant owner was contacted by the police and stated that he had no intention of selling roadkill meals to his customers. Because the deer was butchered outside the restaurant the authorities decided to drop the matter. The restaurant owner also stated he was not aware of any prohibition against eating roadkill; he merely wanted to try something new.{{cite web | url=http://www.upi.com/Odd_News/2016/01/21/North-Carolina-restaurant-owner-apologizes-for-bringing-in-roadkill-deer/1191453400676/ | title=North Carolina restaurant owner apologizes for bringing in roadkill deer | author=Ben Hooper | work=UPI | date=January 21, 2016 | access-date=January 31, 2016 }} In many areas in the United States it is illegal to consume roadkill.

{{main|Ahimsa|Nonviolence}}

Ahimsa is an important tenet of three Indian-origin religions (Jainism, Hinduism, and Buddhism). Ahimsa is a multidimensional concept, inspired by the premise that all living beings have the spark of the divine spiritual energy; therefore, to hurt another being is to hurt oneself. Ahimsa has also been related to the notion that any violence has karmic consequences.Stephen H.
