The second phase of the fifteenth meeting of the Conference of the Parties to the Convention on Biological Diversity (COP15) was held in Montreal, Canada, on December 7. The meeting aims to formulate and adopt the "post-2020 global biodiversity framework", which is of great significance for global biodiversity conservation and sustainable development. In October 2021, the first phase of COP15 has been successfully held in Kunming, Yunnan, China. In the second phase of the conference, the theme and logo of the conference will remain unchanged, and China, as the presidency, will continue to lead the substantive and political affairs of the conference. Biodiversity is related to human well-being and is an important basis for human survival and development. To protect biodiversity is to protect human welfare. China is a vast country with both land and sea, which breeds rich and unique ecosystems, species and genetic diversity. It is one of the countries with the richest biodiversity in the world. China has always attached great importance to biodiversity conservation, elevated biodiversity conservation to a national strategy, and implemented a series of powerful measures, with remarkable results. Recently, with the water level of Poyang Lake rising gradually, a large number of wintering migratory birds have arrived, and groups of waterfowl are flying freely in the lake area. "Look over there. The Oriental White Stork, a national first-class protected animal, has black feathers on its wings. Recently, more than 3700 birds have been observed in our wetland reserve!" Zeng Qingfa, the staff of Nanji Wetland National Nature Reserve in Poyang Lake, Jiangxi Province, was particularly excited to see more and more birds gathering in the lake area. Poyang Lake is the largest freshwater lake in China and an important international wetland, carrying hundreds of thousands of migratory birds to winter here every year. Affected by drought this year, the water level of Poyang Lake has dropped. Migrant bird conservation workers around the lake have taken corresponding measures to "save water for birds" in advance, and staged vivid biodiversity conservation stories. China has been taking action to protect biodiversity. Over the past 10 years, China has promulgated and revised more than 20 relevant laws and regulations, including the Forest Law, the Grassland Law, the Fisheries Law, the Wildlife Protection Law, and the Yangtze River Protection Law, and constantly established and improved the biodiversity protection system, mechanism, and policy system. In 2021, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the Opinions on Further Strengthening the Protection of Biodiversity to promote the building of a beautiful homeland of harmony among all things. The judicial protection of biodiversity has been continuously strengthened. A few days ago, the Judicial Protection of Biodiversity in China issued by the Supreme People's Court and typical cases of judicial protection of biodiversity showed that since 2013, courts at all levels have concluded 182000 first instance cases involving biodiversity protection, and protected biodiversity with legal weapons. A series of biodiversity conservation measures in China have been effectively implemented. Huang Runqiu, Minister of the Ministry of Ecology and Environment, introduced that China has innovatively carried out the demarcation of ecological protection red lines. The area of land red lines accounts for more than 30% of the land area, covering important ecological areas. Actively promote the construction of nature reserves system with national parks as the main body, and set up the first batch of five national parks, with a total number of nearly 10000 nature reserves. Establish a complete ex situ protection system such as botanical garden, wildlife rescue and breeding base, germplasm resource bank, gene bank, etc. It has initially formed a national biological diversity
