A different take on “junk food”

What a clever idea! I just finished reading a short piece in The Economist about a program in Mexico City that allows residents to “barter” their recyclables for fresh produce. I am seriously considering how Harvest Stewards might incorporate such an element of exchange in our food ministry. It seems like a great idea. Just to be clear, there's virtually no way at all that the market prices for recyclable materials could cover the cost of the foods delivered. But right now we're just giving them away anyway, so it certainly couldn't cost more.
