The city of Wuhan in central China's Hubei Province will apply for the 2021 Wetland City Accreditation of the Ramsar Convention, the municipal forestry bureau announced. The announcement was made as the city joined the global "Earth Hour" campaign Saturday night by turning off lights on major landmarks. Wuhan, which sits at the confluence of the Yangtze River and its longest tributary Han River, boasts about 1,624 square km of wetlands, accounting for 18.9 percent of the city's total area. The bureau said Wuhan's wetlands are home to more than 400 wild animal species and over 400 plant species. A total of 18 cities from seven countries were honored as international wetland cities in 2018. Six Chinese cities were among the list, namely Haikou, Harbin, Changde, Changshu, Dongying and Yinchuan. (Xinhua/Wang Jianhua)
