Holy cow

"About 8,000 years ago, the relationship between cows and humankind began with the revolutionary advent of domestication in Mesopotamia, the Indus River Valley, and Africa. There were many possible candidates for the job but only the cow fit the specific criteria humankind needed: not too flighty, breeds well in captivity, grows at a good pace, not aggressive, requires a low maintenance diet. Cows provide just about all of our basic needs, from milk and meat to muscle. Today there are about 1.5 billion cows in the world. In many different countries humans and cows have formed close relationships. This film explores how we've changed the cow and how the cow has changed us.--From publisher's description."@en

Societies which learned to domesticate the cow prospered, while those that did not were left behind. ... evolved to eat pretty much anything and miraculously transorm it into milk and meat, and a whole range of other products that sustain our daily lives ... valuable commodity to some, religiously revered by others, it is a beast of burden, a means of transportation, a way of life.""
