Cassandra Willyard, reporting for Studio 360:

Growing celery in a skyscraper may seem a bit unnatural, but so is growing celery in a field, Despommier argues. “The act of farming is totally unnatural,” he argues. “The moment you start to replace everything with just one thing — like wheat or rice or corn or lettuce — you create problems.”

Not sure I agree with that statement entirely. Fortunately, Willyard was kind enough to give me a rebuttal.
