The Marine National Park Headquarters is responsible for the promotion of environmental conservation and education on the Dongsha Atoll National Park. In a nod to World Oceans Day on June 8th and to call out the public to respect life and protect the ocean, the MNPH cooperated with the Dongsha Command of the South Coastal Patrol Office of the Coast Guard Agency, Executive Yuan, from June 7th to 9th to hold the "Best of Dongsha" beach cleaning event at the Dongsha Island, restoring the pristine beauty of Dongsha's white beaches through practical actions.

The Dongsha Atoll National Park is Taiwan's first national park dedicated to the conservation of the marine environment. It is also the only large coral reef atoll in the northern part of the South Sea, and it acts as a key habitat for the distribution and continual perpetuation of West Pacific marine organisms. The Dongsha Management and the CGA periodically perform beach cleanups to reduce the effects of marine pollution on the organisms. The event promoted the significance of World Oceans Day by caring for the ocean through practical actions and taught us how we can learn to protect marine ecology through self actions.
