The environment and humans are interdependent. Without humans, the environment has no meaning and without the environment, human cannot imagine their existence on earth. This shows a direct relation between the both. But several human activities from the last few decades, on land, air, and water polluted the Environment. These all cause a huge loss of human lives and affect human health in terms of different communicable and non-communicable diseases. All these are constantly degrading human and environmental health. For good human and environmental health, everyone should be aware of holistic health and follow a healthy lifestyle. In this sense, the responsibility of Students of Teacher Education (STE) gets doubled in the sense that they prepare teachers, students, and citizens for their future regards. Therefore, it becomes necessary for STE to be aware of the term Sustainability and all SDGs, which ensures a sustainable livelihood for every individual. The objective of this study is to find out the perception of STE towards Sustainable Development Goal 3 - Good health and well-being. The sample comprises 113 STE (B.Ed. and M.Ed. students) of HNB Garhwal University, Srinagar. The quota sampling method has been taken to select the sample and Data has been collected through a self-developed questionnaire which consists of the items based on SDG-3. The present study will be helpful to train STE accordingly.
