In our day, there are stresses and fractures of the human-animal bond, and some forces at work would sever it once and for all. They pull us in the wrong direction and away from the decent and honorable code that makes us care for creatures who are entirely at our mercy. Especially within the last two hundred years, we've come to apply an industrial mind-set to the use of animals, too often viewing them as if they were nothing but articles of commerce and the raw material of science, agriculture, and wildlife management. Here, as in other pursuits, human ingenuity has a way of outrunning human conscience, and some things we do only because we can--forgetting to ask whether we should.
