This hotel brand grows coral using electricity. They've released nearly 6,000 turtle hatchlings into the ocean. They've won over 700 international spa awards. And their very first resort was built on a toxic tin mine. This is Banyan Tree. In the 1980s, Ho Kwon Ping and Claire Chiang bought 222 hectares of abandoned tin mine in Phuket, Thailand. The land was poisoned, barren, and environmentally devastated.
