Apartment-dwelling urbanites may be surprised to learn how significant lawn care is to the American economy, generating more than $10 billion in annual sales of pesticides, fertilizers and other products. Steinberg, an environmental historian, is aiming for the grassy equivalent of Fast Food Nation
, with one key difference—while people know junk food isn't good for them, they may not be aware that most lawn care products are not only unnecessary but may actually harm soil and turf. He particularly damns the lawnmower industry, revealing how manufacturers "worked tirelessly to mislead the American public" for years in order to avoid the expense of installing safety features that could prevent severed fingers. Steinberg's subjects range from the postwar boom in suburban lawns to contemporary debates over noisy leaf blowers, and he mixes cultural history with personal lawn-related experiences in Long Island and Ohio, where some people maintain putting greens in their backyards. (Not surprisingly, Steinberg points out, golf courses are "the most intensively managed lawns in America.") There's plenty of muckraking outrage, but it's delivered in a friendly, engaging voice that might just win over skeptics. 40 illus. (Mar.)
