Hong Kong serves as the epicenter for activity surrounding a number of endangered species. One such species is the Chinese white dolphin, which is threatened by reclamation in the form of construction projects like the third airport runway and the Hong Kong-Zhuhai-Macau Bridge. Another endangered species with close ties to Hong Kong is the elephant. Hong Kong is viewed by the international community as the center of the illegal ivory trade, which has damaged the city’s reputation. A route from Hong Kong to Macau, then to Zhuhai, is commonly used by smugglers to transport ivory to mainland China.
