The key argument of Robert Gottlieb's Environmentalism Unbound is that an integrated focus on pollution prevention and environmental justice can lay the groundwork for fundamental environmental and social change (p. xiii). The aim is to develop a common vision and a more “embracing language” for environmentalism that is more broadly appealing than a mainstream focus on nature and species and more broadly applicable to a range of environmental and social issues. Such an expanded environmental discourse—integrating the workplace, the social, and the ecological—would make for an unbounded and more successful environmentalism. This is another wonderful offering by Gottlieb, right up there with his Forcing the Spring (1993). The recognition of diverse discourses of environmentalism and social justice is a challenge to movement strategies, and Gottlieb takes on the issue with a focus on both a broad vision and everyday practice.
