Writing in an informal, sometimes charming tone, Sherman (In the Rings of Saturn
) offers a wide range of material about the air we breathe. He explains the way the body processes oxygen (and looks at why some babies have difficulty taking their first breath). Then he explores scientists' growing understanding of air through the centuries, from Aristotle, who believed that the Earth literally exhaled vapors that, when trapped below Earth's surface, became metals, to the 18th-century French chemist Lavoisier, who unseated phlogiston in favor of oxygen as the part of air that caused fire. But even as air was being studied, Sherman says, global forces were making it less breathable. The author describes the killer fogs that engulfed London in the 19th century due to the mass burning of coal; the Germans' use of chlorine gas at Ypres in WWI; and nuclear testing, which has devastated air quality in many areas of the world. Sherman also provides an overview of regulatory attempts to create a healthier environment, from the efforts of Victorian-era feminists who promoted pure air to the troubled history of the Clean Air Act in the U.S. In a thoughtful and engaging manner, and without writing like an environmental polemicist, Sherman sheds light on a substance that is becoming more and more opaque.
