The authors may reach a bit when they try to sound less square, likening the buying of compact fluorescent light bulbs to “an upgrade on your iTunes software.” But they make the science relevant and enjoyable with abundant visuals and conclude with some meaty ways for kids to make a difference. The old standbys are all there (switch light bulbs, recycle, use canvas bags at the grocery store). But I smiled on noticing something new: the authors suggest some “sustainable careers” kids can consider, like meteorologist and “glacial geologist.”

Hey, no problemo. The bacteria will gladly clean up whatever mess we leave behind.

Hmm. I'm afraid "Glacial Geologist" is a quickly shrinking field. These do sound like great books, though.
