Scientifically, the term "organic food" is meaningless. It's like saying a "human person". All food is organic. All plants and animals are organic. Traditionally, an organic compound is one produced by life processes; chemically, it's any carbon-containing molecule with a carbon-hydrogen bond. Plastic and coal are organic, a diamond is not. So when we refer to organic food in such a way to exclude similar foods that are just as organic chemically, we're outside of any meaningful scientific use of the word, and are using it as a marketing label.
I want to stress that I am not opposed to organic food. It is generally a perfectly fine product. I do have objections to the way it's marketed: It's an identical product, sold at a premium, justified by baseless alarmism about standard food. Whether you agree or not that this alarmism is baseless, you should at least agree that that would be an unethical way to promote a product that offers no real benefit. I choose not to reward this with my food-buying dollar. People who willfully seek out the organic label when buying food are being taken advantage of by marketers employing unethical tactics.
The biggest misconception is that organic farming does not use fertilizer, herbicides, or pesticides. Of course it does. Fertilizer is essentially chemical nutrient, and the organic version delivers exactly the same chemical load as the synthetic. It has to, otherwise it wouldn't function. All plant fertilizers, organic and synthetic, consist of the same three elements: nitrogen, phosphorus, and potassium. Referring to one as a "chemical" and implying that the other is not, is the worst kind of duplicity, and no intelligent person should tolerate it.
