An episode of the PTS show Our Island is shot in the mountains of Hualien, where a deep hollow exists right in the green forests. The hollow is the place for cement exploitation. We are shocked and impressed at the scene even after years and begin to consider the issue of mountains' over exploitation. Even though the environmental group fiercely protests, people still forget as time goes by. If the harm to the land won't disappear, should we take some actions? The problems and the harms cannot be ignored. Bearing that in mind, we make this work to lead the audiences to think again the relationship between people and their land and the boundary for reasonable development.
