Through the Far Eastern Curlew and the endangered Taiwanese white dolphin, this documentary explores the changing ecology of Changhua’s western coast. Spanning over 30 years of research and environmental activism by ornithologist Dr. Tsai Chia-yang and the personal journey of returning environmental advocate Wu Hui-chun, it traces the region’s transformation from 1980 to 2020, encompassing massive land reclamation projects, industrial development, and controversies surrounding renewable energy in wetlands. Reflecting Taiwan’s broader coastal environmental history, the film revisits past mistakes and considers how confronting them might open possibilities for a more sustainable future.
