An island in Phuket region (Source: expedia.co.in)
The three islands, namely Koh Khai Nai, Khai Nok and Khai Nui, cover a total of 246 coral reefs.
All of the infrastructure serving tourism activities on the islands were removed after about 80 percent of the coral reefs had been damaged.
According to the Department of Marine and Coastal Resources (DMCR), up to 60 speed boats had been used daily to serve the tourists.
Other activities, such as snorkeling and dropping anchor in the water or collecting coral, severely destroyed the marine ecosystems.
