Plenty of people can attribute South Asian pilgrimages to a shirtless Di Caprio's discovering of Thailand's Maya Bay in the film "The Beach". There's no loss of irony that fictional character Sally (who wished to conceal this paradise from bulldozing backpackers) was somewhat right. Boat anchors have been damaging Maya Bay's coral for years and tourists often leave rubbish, despite multiple signs and threats of repercussions. Thai authorities have since been forced to close the island to allow it a brief respite, although environmentalists warn that a June to September break is not long enough. This isn't the first time the authorities have clamped down on deteriorating islands; three years ago they closed Koh Yoong island for similar reasons and since 2016 Similan Islands National Park has been off-limit to both visitors and divers.
