It is individual responsibility to face reality. Most people attempt to maintain a delusion that "humans" are more noble than every other creature on this planet. Surely Mankind is not.

I have hunted since the age of 12 when I shot my first deer.  I have never avoided or denied underlying sadness that accompanies killing an animal. I accept it, and facilitate respect for animals in providing best environment for  livestock, and improving habitat for wild animals.  In throwing the switch from friend to food, the choice of consciousness and accountability is enacted.  Man belongs to the environment, the environment does not belong to Man.

Emotions are products of thought processes.  Ego misidentification manfests dysfunction when thoughts about killing animals for food are assembled into a story of who we are.  Ego being one's "story" of how humans are noble.  Surely I am not noble.  How could I be?  I am not a story.  Humans perpetuate a dysfunctional psychological need to be dislocated from their food supply.  The ego wants to be real.  The individual suffers to "be the story".  Ego is always dysfunctional.  Better to kill the ego and just "be".

Have you ever considered a hypothetical "UFO analysis of the human race"?  The Jimi Hendrix song "Third Stone From The Sun" portrays a UFO landing.  Rationally, aliens decide  that the only intelligent lifeform on Earth are cackling hens.  Responsibly, aliens decide to "put an end" to Earth's civilization, stating: "and so you will never hear surf music again".  A moral story.

To the disappointment of some, I look forward to eating chickens.  However it remains my experience, that much can be seen when looking into the eye of a chicken.  Someone definitely looks back.    Be it friend and food.
