I live in a tropical paradise.  Every two days I run to Ao Muang.  Each time I see many tourists going to and fro and falling off their rental scooters.  They never have any litter with them.  Where then do they put their empty water bottles?  Clearly on the ground.  Yesterday I found some empty pig feed sacks and filled one with 10kg of beer bottles and cans, motor oil bottles and even tubes of toothpaste.  Obviously we all need to start doing this and stop marring our idyll.  You may be on holiday, but we live here.  Project AWARE, Dive Against Debris and Save Koh Tao are not fashion statements or opportunities to improve your PADI Course Director Training Course application ranking.  It's about a way of life.
