Seaweed is a living organism that is symbolic of the clean water zone in the depths of the sea, and is also one of the origins of marine organisms. Wando Seaweeds Expo includes a range of displays of marine algae, discussions over environmental concerns such as climate change and global warming, and prospects for “green growth” through seaweed. The expo shows the importance of seaweed as a food resource, and aims to bolster the domestic seaweed industry. The expo also aims to make Korea a leading nation in the seaweed industry through an active response to the growing demand for Korean seaweed. A range of activities have been arranged for visitors to the festival, held in the Wando Port district, which include an exhibition, hands-on programs, an international forum, conference, and other events. It is the first expo to be centered on the theme of a variety of seaweed including dried and sea mustard. The seaweed expo will be a venue for the exchange of seaweed-related information and technology for participants representing 60 corporations in 20 countries around the world.
