According to a recent study by Brigham Young University, it's possible that Great Salt Lake could dry up completely in the next five years.
Less water going in means higher concentrations of salt and minerals, which threatens the crucial ecological role saline lakes play across the West, as well as the health of the people who live nearby.
Seal Island, South Africa. As the name suggests, Seal Island located in the False Bay off the southern coast of South Africa, is home to Cape Fur seals. They chatter, fight, and defecate around the barren rocks in the island, thereby making it a very smelly place.
Water experts say it's going to take more than one big year to fill the Great Salt Lake. SALT LAKE CITY — Ever since The Great Salt Lake hit its lowest water level on record in November 2022, concerns over things like arsenic in the exposed lake bed have only grown.
Within years, the lake's ecosystems could collapse and millions will be exposed to toxic dust contained within the drying lakebed, unless drastic steps are taken to cut water use. A team of 32 scientists and conservationists caution that the lake could decline beyond recognition in just five years.
A new scientific report warns the lake is on track to disappear in the next five years, unless water use is cut by as much as 50% annually. I don't know of any other environmental threat that's moving this quickly, said Bonnie Baxter, a Westminster College biochemist and one of the authors of that study.
Great Salt Lake is between 3.5 and 8 times saltier than the ocean. The organisms that live in the water have special adaptations that allow them to survive such saline conditions. Air blocks much of the sun's DNA-damaging ultraviolet light from reaching the surface of the earth.
Because of the abundant algae and halophiles, as well as the high salinity, the lake does not support fish — but it teems with brine shrimp and brine flies, which provide essential nutrition for migrating birds.
