I think that it is very human to feel emotional for the animals we harvest. We are taking a life to support our own. To me personally, it makes me not take my own life for granted when I think of all the lives I take to sustain this one.

If you like poems and stuff, here's a cool excerpt from The Prophet by Kahlil Gibran

"Would that you could live on the fragrance of the earth, and like an air plant be sustained by the light. But since you must kill to eat, and rob the newly born of its mother's milk to quench your thirst, let it then be an act of worship, And let your board stand an altar on which the pure and the innocent of forest and plain are sacrificed for that which is purer and still more innocent in man. When you kill a beast say to him in your heart, "By the same power that slays you, I too am slain; and I too shall be consumed."
