Concerned about reef damage caused by scraping anchors, Halas invented an alternative mooring system and has helped install it all over the world, from Malaysia to Egypt. Over fifty different coastal regions now use his method. In these photos, he teaches conservation groups in Vietnam and the Philippines to install the reef-friendly buoys. Photo by Than Ha.
