Nam Sang Wai is located in Deep Bay in the Northern New Territories. Apart from being a local scenic hotspot where the people of Hong Kong go there for picnic, photography and enjoying nature, it is also a biodiversity hotspot for birds. It also has the most extensive reed bed in Hong Kong. Despite its importance, developers are proposing to build low density residential housings in Nam Sang Wai. In this programme, students will get to know the conflicts between nature conservation and development.
