Frank Zelko's Make It a Green Peace! The Rise of Countercultural Environmentalism is a thought-provoking addition to the history of the modern environmental movement. Often understood as the “environmental decade,” the 1970s saw the institutionalization of what Hal Rothman, in Saving the Planet: The American Response to the Environment in the Twentieth Century (2000), termed “full-stomach environmentalism.” Works on the mainstream embrace of environmentalism such as Samuel Hays's Beauty, Health, and Permanence: Environmental Politics in the United States, 1955–1985 (1987) and Adam Rome's The Bulldozer in the Countryside: Suburban Sprawl and the Rise of American Environmentalism (2001) have focused on how middle-class concerns over pollution, open space, and energy shaped environmentalism during the decade. In contrast, Make It a Green Peace! joins studies such as Andrew Kirk's Counterculture Green: The Whole Earth Catalog and American Environmentalism (2007) in exploring the tremendous influence of the counterculture on environmental thought and activism, which redefined the modern environmental movement.
