Koh Pling, popularly known as Pling Island in Thailand, and the coral reefs encircling the Sirinart National Park in Phuket have been temporarily closed for tourists. In the recent past, aquatic life -- from coral reefs to fish -- in the eastern gulf coast of Thailand have been negatively impacted due to rising sea surface temperatures amid the heatwave, which is a cause of worry for local communities and environmentalists.
