During the ten thousand years since humans began domesticating animals, we have kept them primarily to supply our material needs.

In 1969, the bar of human hubris was raised significantly when William H. Stewart, surgeon general of the United States, announced: “The war against infectious diseases has been won.”1 Considering that bacteria, viruses, and protozoa had a more than two-billion-year head start in this war, a victory by recently arrived Homo sapiens would be remarkable. ...
