The National Certificate of Action for Young People's Marine Protection Science Popularization is an initiative aimed at promoting marine environmental protection in China. In recent years, marine environmental problems in China have become increasingly prominent. In order to strengthen the guidance and training for young people to participate in the protection of the marine environment, a certificate was established. By providing relevant marine knowledge, strengthening environmental awareness, and encouraging practical actions, young people are encouraged to actively participate in specific popular science activities and practices, and they are encouraged to become responsibility bearers who care about, love and actively safeguard our precious ecological resources such as the atmosphere, waters and land.
