A transformativeAfrica creative writing activity within a Collaborative Online International Learning (COIL) project between students in Durban, South Africa, and Sheffield, England sheds light on how young people from the Global South experience ecoanxiety. Nosipho Faith Makhakhe explores ways to develop understandings of sustainability and increase eco-literacy through reflection and writing exercises. She provides strategies for exploring culturally specific perceptions of mental health within a cross-cultural context in which climate change is understood as a mental health threat multiplier. Learners who experienced Durban’s worst climate change-induced flooding in April 2022 use poetry writing to express associated feelings. The concept of ecoanxiety allowed students to process their emotions regarding changing weather patterns and the associated threat. Makhakhe discusses her students’ interest and surprise when comparing politics and policies around environmental preservation and infrastructure with corresponding structures that are not necessarily more functional or effective in the United Kingdom.
