True, but that comes at the expense of local farmers in places like, say, Ohio where it's not economical to grow strawberries because California has so much sun and can grow them better - the whole proposition rests on cheap energy and water. If California farmers paid more in costs it's likely that other regions with perfectly fine growing climates could just restart production and then we'd solve a love of problems. California growing all of these fruits and vegetables is basically "the suburbs" in a nutshell.
