In this Wednesday, Dec. 4, 2019, photo, sightseers plays on a sandbar in the Mekong River in Nakhon Phanom province, northeastern Thailand. Experts say the aquamarine color the Mekong River has recently acquired may beguile tourists but it also indicates a problem caused by upstream dams. The water usually is a yellowish-brown shade due to the sediment it normally carries downstream. But lately it has been running clear, taking on a blue-green hue that is a reflection of the sky. The water levels have also become unusually low, exposing sandbanks in the middle of the river. (AP Photo/Chessadaporn Buasai)
