Meat is animal flesh that is eaten as food. Humans have hunted, farmed, and scavenged other animals for meat since prehistoric times. The establishment of settlements in the Neolithic Revolution allowed the domestication of animals such as chickens, sheep, rabbits, pigs, and cattle. This eventually led to their use in meat production on an industrial scale in slaughterhouses.
Animal farming (including meat production) is one of the most significant contributors to the most serious environmental problems, including global warming, pollution and biodiversity loss, at every scale from local to global.Meat is mainly composed of water, protein, and fat. It is edible raw but is normally eaten after it has been cooked and seasoned or processed in a variety of ways. Unprocessed meat will spoil or rot within hours or days as a result of infection with, and decomposition by, bacteria and fungi.
Meat is important to the food industry, economies, and cultures around the world. There are people who choose not to eat meat (vegetarians) or any animal products (vegans), for reasons such as taste preferences, ethics, environmental concerns, health concerns or religious dietary rules.
