6 students joined an eco-tour organized by WWF-HK and the Coral Academy of the Chinese University of Hong Kong at the Hoi Ha Marine Life Centre, which is Hong Kong's one and only marine research and education center built on the water. This allowed the students to learn about the importance of coral to the ocean. Additionally, the students were able to board a glass-bottom boat and admire the precious coral and marine life in this special aquatic environment. Also, they learned how to conduct water testing in order to understand the impact of environmental changes on coral growth.
