When I’m contemplating the many ways civilization, and even humanity, might collapose, it doesn’t help to be nudged along by NASA scientists telling me I’d better freak out about the likelihood that one of about 20,000 asteroids will fall to Earth and destroy a major city. (Is that all?) They spend more than $4 million a year at NASA already looking for asteroids, but they want at least a billion dollars to find them all by 2020.

Robert Reich’s article in The American Prospect on NASA’s asteroid report is very well timed, since I also happened to have just finished reading the latest in my series of apocalyptic novels this week — a newish young adult novel by Susan Beth Pfeffer called Life As We Knew It.

See that looming moon on the cover? In the fictional world of the book, scientists told the people of Earth that an asteroid would hit the moon, but they made a little miscalculation.

Last Fall I read another novel of teen post-apocalyptic survival, Into the Forest by Jean Hegland. Life As We Know It is nowhere near as bleak, if that can really be said of such a desperate situation. Through the main character Miranda’s diary, we see her make the gradual switch from superficial teen focused on boards on a fan site to becoming an essential member of her own family as they work to survive a nearly impossible situation.

A lot of reviews of Life As We Know It mention that the readers want to run out right then to buy canned soup and collect firewood. The focus on remaining resources definitely makes it clear that planning helped some survive. Whatever it takes to get people to prepare themselves for catastrophic disaster or more common emergency.

I am keeping my library account on notice to find the companion novel recently finished but yet to be published.
