We live in an age when you can prowl the streets of major cities and find human beings offering themselves in store windows, or just reach for the yellow pages and have them delivered. It is the same mindset at work, spreading in our world, and after a while this attitude can find nothing very special about anything or anybody, let alone whales.

Sometimes tradition and habit are just that, comfortable excuses to leave things be, even when they are unjust and unworthy. Sometimes--not often, but sometimes--the cranks and radicals turn out to be right. Sometimes Everyone is wrong.

Regarding factory-farmed animals We owe them a merciful death, and we owe them a merciful life. And when human beings cannot do something humanely, without degrading both the creatures and ourselves, then we should not do it at all.

An author describing the methods of intensive farming, or the excesses of sport hunting, or even the harsher uses of animals in science writes with confidence that most readers will share his sense of concern and indignation. Sounding the call to action-convincing people that change is not only necessary, but actually possible-is more problematic. In protecting animals from cruelty, it is always just one step from the mainstream to the fringe. To condemn the wrong is obvious, to suggest its abolition radical.

Perhaps that is part of the animals' role among us, to awaken humility, to turn our minds back to the mystery of things, and open our hearts to that most impractical of hopes in which all creation speaks as one.

If we are defined by reason and morality, then reason and morality must define our choices, even when animals are concerned. When people say, for example, that they like their veal or hot dogs too much to ever give them up, and yeah it's sad about the farms but that's just the way it is, reason hears in that the voice of gluttony. We can say that what makes a human being human is precisely the ability to understand that the suffering of an animal is more important than the taste of a treat.

The smell of factory farms . . . many notice these places only when the odours reach their homes, affecting their own quality of life. We create these animals for our profit and pleasure, playing with their genes, violating their dignity as living creatures, forcing them to lie and live in their own urine and excrement, turning pens into penitentiaries and frustrating their every desire except what is needed to keep them breathing and breeding. And then we complain about the smell.
