The Save Koh Tao Marine Branch is a community group on Koh Tao who gives information about coral reef education, research and restoration projects around the island. The "Green Signs" is one of the projects of the community group with the main goal to educate tourists around the island to keep Koh Tao clean. The signs can already be found around different diveschools who helped creating them, but in the end we hope to find them everywere around the island. Here a picture of a Green Sign which can be found around Sunshine Divers.
