This video was recorded on March 20, 2016 and published by CORE Sea, a marine conservation and research organization focused on Southeast Asian (predominantly Thailand) reefs.  As sweet as the video is, it’s a little depressing to see so much man-made ocean debris; the snorkeler is even cutting the discarded netting with a broken glass bottle.
