Sowing Seeds of Compassion - by Joanne Stepaniak - "There is a degree of irony in selectively applying compassion. It is as if there were truth to the slogan George Orwell's characters in Animal Farm came to believe, 'All animals are created equal, but some are more equal than others.'

Their concern is solely for the dolphins (apparently because they are mammals, like us) with no regard for the dead tunas."
