Just out of curiousity (my own), I'd like to ask a questions I've never heard either side of the GE debate answer. Here ya go.

Since agriculture became "big business" around 10,000 years BCE or so, crops have been cultivated to give us the current types of corn (maize), wheat, potatoes, tomatoes, and so forth which we enjoy. Without this hybridization, crops would be far more liable to disease and produce far less yield than they do. Hybridizing plants is done by altering their genetic makeup, selecting for what humans consider desirable traits and breeding undesirable traits out of the plant. Granted, hybridization takes far longer than genetic engineering but, given that the end result in either case is a changed plant (and possible extinction of the original strain), what's the difference? Other, of course, than that one is done in a lab and the other in a field.
