Last night on "King of Queens" (CBS), Doug befriended a chicken, and subsequently stopped eating chicken. He told a friend, "Hey at least it wasn't a cow", upon which the friend shows him graphic footage of cows being slaughtered (only his reactions were on camera). Doug eventually becomes an animal rights / environmentalist FREAK and drives everyone around him crazy.
There was a subplot about competing hamburger companies trying to outsell
each other, eventually, Doug does slip and eat a burger, but in the final
scene, he is seen rescuing his old chicken friend from a Chinese market.
There are indeed ways to put the hard facts in the public's face without
having them look away, but it takes brave, talented writers & artists.
