One of the cool things about using "natural disasters" as a theme in your coursebook is that, sooner or later, "what goes around" is somehow likely to "come around" again - relieving some of the stress writers and publishers experience in terms of ensuring textbook content stays fresh and relevant in an ever fast-forwarding world.
