Ko Phi Phi Lee

This guide to Ko Phi Phi Lee in Krabi opens with a blunt measure marine biologists use for reef health, counting sharks, and the zero blacktip reef sharks left in this bay before 2018. It follows the Thai government's decision to close the bay entirely, first for months and then for years, while marine biologist Thon Thamrongnawasawat and volunteers hand-grafted coral back onto the ruined seabed. Much of that coral was grown offshore on a nearby island before divers carried it here by hand.
