Do you eat organic?

I do, when I can. I prefer my local Whole Foods Market to our conventional supermarket chains. And, often, I prefer smaller, local organic markets even to WFM. I do it for my own health, of course, but "sustainability" -- economic, environmental -- is certainly a good enough reason to seek out and support the organic-food movement.

But is there a dark side to buying organic? Slate tackles that question here. Don't let some admittedly valid points stop you from buying and eating organic, but, clearly, there's more to "sustainability" than meets the righteous conscience.
