Completing this course has been a truly transformative experience for me. Before starting, I viewed sustainability primarily through the lens of environmental preservation due to my current career as a public greenery manager. However, the variety of learning topics and the emphasis of applying system thinking throughout the course has broadened my understanding and perspectives on sustainability, showing me how interconnected social, economic, and environmental factors are in achieving sustainable urban development. Equally important, I have also gained many friends from various walks of life and treasured our fun times together in meaningful class discussions, group projects and field trips.

Thanks to this course, I now feel empowered to contribute to a more sustainable future, both professionally and personally. I highly recommend it to anyone who wants to make meaningful and positive differences for our natural and urban environment.
