In my first post on the Heirloom Exposition, I gave an overview covering what heirloom means. In the second post, I covered what is the antithesis of heirloom - genetically modified organisms. To wrap up my soapbox lectures on the heirloom festival before returning to more neutral ground, I’d like to talk about the point of heirloom – why is it important? Is it sustainable – can it produce enough to feed the world? What does the concept cover that we aren’t already doing? Why do people want to farm the heirloom way?
