There have been various interesting and worrying reports on the environment and the changes that are occurring every second on this Earth. Recently, two news updates caught our eye; about the mass fish deaths in Singapore and the Lake in Turkey that has turned blood red.

Close to a thousand fish went belly up at Bishan-Ang Mo Kio Park on last week, in a repeat of a similar incident last year.
National water agency PUB said that the latest incident at Kallang River, which runs through the park, affected about 800 to 900 fish of varying sizes. They were mainly cichlids, a diverse family which includes the popular aquarium fish luohan and the food fish tilapia. Fish specimens have been sent to the Agri-Food and Veterinary Authority of Singapore for examination, and investigations are ongoing, said a spokesman for PUB. It is monitoring the situation.
A popular salt lake in Turkey recently turned a deep red color thanks to an enormous bloom of Dunaliella salinas algae.
Saline lake Tuz Gola, the second-largest lake in Turkey, is slowly evaporating amid the summer heat, according to Stony Brook University marine ecology research professor Dr. Christopher Gobler. “Because the lake is losing water, the salinity is getting higher and higher, which kills off a lot of the plankton that normally eat this red algae,” Gobler said. “So now, the algae is thriving and will probably red until the lake fully evaporates, probably next month during the peak of summer heat.”
During dry months, the lake often attracts tourists who can literally walk on the salt flats until water starts coming back during winter months, Gobler said. But for now, tourists can wade in the water that filled with harmless algae, according to Gobler. “I wouldn’t recommend drinking the lake’s water, but some people actually grow Dunaliella salinas algae for its antioxidant properties,” Gobler said.
He added that pink flamingos currently at the lake can thank the “incredibly colored” algae for their vibrant color. “The lake is home to pink flamingos, and the reason they’re pink is because they get their coloration through the food web, which starts with the algae,” he said. “This algae gets eaten by plankton, which gets eaten by fish and other organism that then get eaten by flamingos.”
