Organizing Cools the Planet offers a challenge to all concerned about the ecological crisis: find your frontline. This booklet weaves together stories, analysis, organizing tools, and provocative questions, to offer a snapshot of the North American Climate Justice movement and provide pathways for readers to participate in it. Authors share hard lessons learned, reflect on strategy, and grapple with the challenges of their roles as organizers who do not come from frontline communities but work to build a movement big enough for everyone and led by the priorities and solutions of low-income people, communities of color, Indigenous, youth, and other constituencies most directly impacted by the crisis. Rooted in the authors’ experiences organizing in local, national, and international arenas, they challenge readers to look at the scale of ecological collapse with open eyes, without falling prey to disempowering doomsday narratives. This booklet is for anyone who wants to build a movement with the resiliency to navigate one of the most rapid transitions in human history.
