Education for Global Citizenship is about living as though the future mattered. This evaluates learner reactions to a tree-planting exercise that invites reflection upon hopes for the world, personal responsibilities and acting locally while thinking globally. Participant hopes concerned: environmental sustainability, peace on earth, then the welfare of future generations and personal wellbeing. Global citizenship concerns included sustainability, social justice, interdependencies and personal responsibilities. Some participants envisaged exercise outcomes to be mainly practical, others personal, such as reflection on lifestyle choices. Off-campus sessions generated higher grades, more concern for giving back to/defining a role in nature and volunteering.
