The Department of National Parks, Wildlife and Plant Conservation claims to be investigating ways to control tourist numbers amid concerns that visitors are destroying the environment at marine tourism spots. The move was prompted by marine scientist Thon Thamrongnawasawat, who posted photos of large numbers of low-season tourists packed onto small Maya Beach. According to Mr Thon, during low season 2016, about 5,000 tourists a day crowd onto Maya beach, which is just 250 metres long and 15 metres wide. The beach has 14 available toilets. Tourists are worth 1.6 million baht a day to the park. Thon said that state agencies were running campaigns to drum up tourist numbers with no regard for the environment's carrying capacity.
