Young people’s ongoing, necessary confrontation with painful and distressing realities exacerbated by ecological precarity in diverse contexts has profound implications for formal education systems. Additionally, educational policy in many contexts has been slow to respond to the urgency of addressing climate change, nor has most policy robustly conceptualized a vision for climate justice education. Centering the voices of three young climate justice activists (ages 16–20) in Canada through a qualitative study, this paper explores possible educational responses that recognize the embodied consequences of climate injustice and inaction on youth mental health and well-being. Through their encounters with activism in collective, justice-centered movements, these young people articulate how their commitments to creating more life-affirming and equitable realities by challenging current economic and political structures and discourses are integral dimensions of their efforts to be and feel well (hopeful and purposeful) in a context of pronounced uncertainty and distress. Despite these possibilities, youth participants describe the overwhelming and complex emotions they are grappling with as they face dispiriting projections for the future. These growing challenges are an opportunity to reconsider common “apolitical” and individualized approaches to citizenship, climate and environmental education. Findings suggest that supporting youth to act thoughtfully and impactfully in transforming cultural, economic and political structures and systems that reproduce harm can be a way to nurture meaning, purpose and hope. Additionally, youth participants advocate for integrating robust resources and support within formal education institutions to assist in collectively processing the emotional and psychological impacts of climate injustice. At the same time, findings suggest that the participating youth did not yet integrate conceptions of ecological interrelationship or interconnection in their approaches, offering possible avenues for further pedagogical development.
