Core Viewpoint - The article emphasizes the importance of mangrove ecosystems and highlights the global and national efforts to protect and restore these vital environments, particularly in China, where significant progress has been made in increasing mangrove area and implementing protective measures [1][2][3]. Group 1: Importance of Mangroves - Mangroves serve as coastal guardians, providing protection against storms, purifying seawater, and maintaining biodiversity [1]. - They play a crucial role in carbon storage and climate change mitigation, earning the title of "marine green lungs" [1]. Group 2: Global and National Challenges - Mangrove areas are declining globally due to coastal development, illegal logging, and environmental pollution, threatening the survival of many species dependent on these ecosystems [1]. - Globally, mangrove coverage is approximately 15 million hectares, with China accounting for only 0.2% of this area, primarily located in five coastal provinces [1]. Group 3: China's Response and Initiatives - China has implemented a series of measures to enhance mangrove protection, including the establishment of the Wetland Protection Law and specific action plans for mangrove restoration [2]. - The country has seen an increase in mangrove area to 30,300 hectares, making it one of the few nations with a net gain in mangrove coverage [2]. Group 4: Future Directions - Continued efforts will focus on strengthening legal frameworks, innovative restoration technologies, and comprehensive monitoring systems to enhance mangrove conservation and restoration capabilities [3]. - The commitment to protecting mangroves is framed as essential for both national ecological health and global environmental contributions [3].
