Environmental pollution and climate change have increasingly become a global threat in recent years, particularly causing significant adverse effects on children's health. The aim of this study is to assess the knowledge and awareness levels of pre-service teachers regarding environmental health issues and to examine how this awareness can serve as an effective tool in combating environmental problems. In the study, the knowledge and attitudes of pre-service teachers towards environmental pollution, climate change, and their effects on children's health were evaluated using the "Environmental Attitude Scale." The survey results show that environmental health education plays a crucial role in raising environmental awareness among pre-service teachers and making them more sensitive to environmental issues. According to the findings, the awareness levels of pre-service teachers regarding the health impacts of environmental pollution and climate change are quite high. However, their awareness of how they can individually develop solutions to environmental problems is found to be lower. In this context, educating pre-service teachers on these issues will enhance their capacity to instill environmental awareness in their students and contribute to raising societal awareness. The results emphasize the need to expand environmental health education programs, not only providing theoretical knowledge but also equipping individuals with the competencies to actively produce solutions to environmental problems. The data obtained from the study reveal that pre-service teachers with high levels of environmental awareness tend to exhibit environmentally friendly behaviors. These results suggest that environmental education can play a critical role in fostering sustainable living habits on both individual and societal levels. It is expected that pre-service teachers with high environmental awareness will transmit this awareness to their students in their future professional roles, leading to long-term benefits in combating environmental issues.
