MELBOURNE, AUSTRALIA - MARCH 27: People take photographs of the pink lake at Westgate Park on March 27, 2019 in Melbourne, Australia. The inland lake turns pink in warmer months thanks to a natural phenomenon. The pink hue happens in response to high salt levels, lots of sunlight and a lack of rainfall. Lake algae, which grows in the salt crust at the bottom of the lake produces a red pigment as part of its photosynthesis process. (Photo by Scott Barbour/Getty Images)
