I took a photo of a page from a children’s book that I was perusing while waiting for the guys yesterday afternoon. You might have to click on the photo to make it a bit larger: but notice the odd supply chain. Some cows on a field (is that really representative of a modern farm?) Next the food magically appears in the grocery store. Note that the food is packaged. And is not the product of the dairy cows. In the final stage, french fries, salad, and meat appear on a plate.
Need I say more?
