Algae Reefs, mainly built by the calcareous red algae, are one the most spectacular landscapes along the coastline of Taoyuan City, Taiwan. Just like the tropical coral reefs, algae reefs in Taiwan also provide similar ecological services, such as fishery, tourisms, education, and coast protection. Nevertheless, a tank docking port for liquid natural gas (LNG) receiving station is planned and readily to constructed by August, 2017 by the Chinese Petroleum Cooperation (CPC) at the Datan District, Taoyuan City, if the environmental impact assessment is approved. Once this project is initiated, there will be over 300 hectares immediately land-filled and subsequently biodiversity and ecosystem lost. The environmental NGOs and local communities at the Datan and neighbor Districts have raised their concerns and protest to the city and central governments regarding to the habitat destruction of mass areas of algae reefs by this CPC-LNG station developmental project.
On June, 8, 2017, the Oceans Day, the environmental NGOs, local communities, and marine scientists gathered at the Datan algae reefs to celebrate this important event with people from the world, and at the meantime to take the action to raise the international attention of the crisis that algae reefs will be dramatically lost due to the CPC-LNG receiving development. The sign of “SOS! ALGAE REEFS” was laid on the beach close to the Datan algae reefs, and the drone flied over volunteers and reefs to record the most important moment of marine conservation action in Taiwan in 2017.
