Just a few days before I arrived in Koh Mak, Trat province, veteran marine ecologist Thon Thamrongnawasawat posted on Facebook about his collaboration with Bang Chak Corporation to rehabilitate a 10 rai field of seagrass around Koh Mak and Koh Kradat to build blue coastal carbon ecosystems. That would allow Koh Mak to get one step closer to joining the list of the Top 100 Green Destinations in the world.
