'"It's not natural, Fullwell." Terry hadn't touched his tea.
"Why, there're many things in our society that are not natural. The dam we built to keep the Ganja River from flooding our little town isn't natural. The wells we've built to give us cleaner and fresher water is not natural. But they make our lives a hell of a lot better, do they not?"'
