What meat-eating (or coffee-drinking for that matter) allegedly does to our character, as the book seems to say, is all a red herring. The only thing vegetarianism asks us philosophically is: Are you okay that something died?
How can we continue to justify the costs of textbooks in an era when "free" is the name of the game, when a simple Google search yields a gaggle of information previously reserved for an elite, doctoral few?
Probably none of us have gone through high school or college without some relationship to that 20th century artifact of learning called the textbook. Today's students are not experiencing the same thing.
