Greenpeace, in collaboration with a local award-winning ecological photography team, spent over half a year producing the environmental documentary "Lantau: The Hidden Treasure of Hong Kong," which documents more than 20 precious species on Lantau Island, including the Chinese white dolphin, the Ruddy Turnstones, Hong Kong Newts, Cattle Egrets, etc. The entire film utilizes aerial shots, underwater filming, and night vision photography to present the most authentic aspects of Lantau Island's vivid ecology and fully guide the public to understand Lantau's rich biodiversity, which is a source of pride for the people of Hong Kong. By documenting the precious features of Lantau Island, it aims to raise public awareness of environmental protection and urban development in Lantau.
