The health benefits of Organics are often less about the process and more about the seeds. Heirloom tomatoes as an example tend to be smaller, and squishier, and more flavorful.

The smaller means you can't produce as many per acre.

The squishier means you lose more in shipping.

The Tastier often accompanies more nutritious.

The Pesticide issue is two fold. (same with herbicides) You could dust your plants with arsenic and call them Organic. That would work well, (and is used in certain organic farms often for strawberries) but the residue would be more harmful even in lower amounts than say a Coal-Tar Pesticide (basically an artificial flavor sprayed on to mimic the smell of a predator, or the flavor of something an insect doesn't like)

Organic != Safe

Traditional != Dangerous

My biggest concern is that we cannot produce enough food via organic farming to feed everyone. If we move too much of the market to Organics, we may end up like the places where 40% of their income goes to food, instead of 4% that we currently enjoy in the US.

My secondary concern is that too many people think "all-natural" or "organic" means safe. NightShade is an all natural herb. Doesn't mean I should brew tea of it and have it at bed time.
