The first supermarket supposedly appeared on the American landscape in 1946. That is not very long ago. Until then, where was all the food? Dear folks, the food was in homes, gardens, local fields, and forests. It was near kitchens, near tables, near bedsides. It was in the pantry, the cellar, the backyard.
Food security is not in the supermarket. It's not in the government. It's not at the emergency services division. True food security is the historical normalcy of packing it in during the abundant times, building that in-house larder, and resting easy knowing that our little ones are not dependent on next week's farmers' market or the electronic cashiers at the supermarket.
That many if not most people.. Who want fresh leafy greens in January buy them at the supermarket after they've been bleached and plastic-bag shipped from California or beyond is not a tribute to modern technology; it's an unprecedented abdication of personal responsibility and a ubiquitous benchmark of abnormality.
In my opinion, if there is one extremely legitimate use for petroleum besides running wood chippers and front-end loaders to handle compost, it's making plastic for season extension. It parks many of the trucks [for cross-country produce transportation]. With the trucks parked, greenhouses, tall tunnels, and more seasonal, localized eating, can we feed ourselves? We still have to answer that burning question.
