I can think of no sadder example of our food paradigm than two posters taped to the window of a California IHOP. One is a colorful photo of pancakes heaped with bananas, strawberries, nuts, syrups and whipped cream with the caption, 'Welcome to Paradise.' Lower down, an 8x10 photocopy states: 'Chemicals known to cause cancer or birth defects or other reproductive harm may be present in food or beverages sold here.' Such signs are posted on many fast-food outlets. Heaven isn't a place on earth, at least not at these drive-throughs.
