In order to pool the public welfare force of loving the sea and enhance the awareness of protecting marine resources, China Ocean Development Foundation, with the support of coastal natural resources departments at all levels, has been organizing "national clean beach public welfare activities" in coastal provinces and cities since 2017. Through organizing well-known marine public welfare institutions and marine volunteers to carry out beach cleaning activities, we can spread the knowledge of marine resources and ecological restoration, and promote all sectors of society to actively participate in the construction of beautiful coastline, so as to form a good situation for the whole society to jointly promote the construction of marine ecological civilization.
