"Pink Pond in Hawaii Raises Environmental Concerns and Attracts Tourists"

A pond in Hawaii's Kealia Pond National Wildlife Refuge has turned pink due to the presence of halobacteria, a type of archaea that thrives in high-salt environments. The pink hue is a sign of environmental stress caused by dry conditions and increased salinity levels. While the water is not likely to pose a health threat to humans, officials have advised against swimming in the pond and consuming fish from it. The color change serves as a warning that the ecosystem is being severely impacted, and experts attribute the phenomenon to climate change and extreme weather events.
