There's a lot of hype out there and while the ideal of organic is a good one, the application is not so.
There's a lot of misinterpretation in the organic world and many of us have decided that the lies are not worth the extra cost and effort.
So BP has loads of banks, and loads of groceries, but clearly not enough demand for Organic Produce, when many best selling authors recommend buying Organic produce.
I guess not too many BP people are familiar with Amazon Best Selling Health books or they choose not to prioritize this.
"Amazon Best Seller" doesn't mean "based upon verifiable scientific facts." It may simply mean "purchased by a lot of sheeple just like the rather nasty author of this comment."
For example, after analyzing 240 studies about the nutritional value of organic food, the authors of a 2012 review study published in the Annals of Internal Medicine concluded that they “[lack] strong evidence that organic foods are significantly more nutritious than conventional foods.” Perhaps the folks in BP choose to believe those studies, rather than a review of Amazon's best seller list.
Or perhaps they choose to support small farmers, local growth and biodiversity through CSAs.
