Otherwise they won't be able to get consumers to buy their products and will eventually go out of buisness.
The last sentence of the first paragraph
Because people don't follow their own advice
Dear President,
I am but a humble turkey. I am a working man, and I have children to feed. I beg of you to pardon me, so that I may raise my sons to be your next feast. Take them, not me! My bones are old, and my flesh rots, but my sons-- maybe they are to your liking. But please- pardon me so that I might be able to save my daughter and my wife! Do not let the turkey species go extinct!
-Your favorite turkey, Turk.
