A large salt lake is on the brink of disappearing: scientists are devising a plan to save it.

A recent study by scientists has revealed the grim reality facing the Great Salt Lake in Utah: nearly two-thirds of its shrinkage is attributed to human consumption of river water, which is essential for replenishing its supplies. This alarming conclusion highlights the anthropogenic factors contributing to the declining water levels of the lake, which has reached record lows twice in the past three years, according to Gizmodo.

Stretching 120 by 56 km and with a maximum depth of just 10 meters, this unique lake has been in decline since the 19th century, but human activities have accelerated its depletion. The research published in the journal Environmental Challenges indicates that 62% of the vital river water for the lake is diverted for human use, with agriculture being the primary culprit.

Notably, 80% of the lake's water is utilized for growing feed crops for nearly a million head of cattle. William Ripple, an ecologist at Oregon State University and co-author of the study, points out that the practice of feeding livestock significantly contributes to the lake's deteriorating condition. Historical factors, such as its division by a railway trestle in 1959 and irregular water inflow from snowmelt in the 1980s, temporarily masked the long-term decline in its state. However, evaporation and inconsistent precipitation continue to exacerbate the issue.

Ripple and his team propose reducing river water consumption by 35% to stabilize the lake's level. They aim to drastically cut the production of alfalfa and grass hay, which would lead to a reduction in agricultural revenues by $97 million annually—0.04% of Utah's GDP. Despite the economic impact, compensation mechanisms for farmers could pave the way for sustainable water source conservation, the authors note.

In addition to its ecological significance, the Great Salt Lake provides 9,000 jobs and generates $2.5 billion annually through mineral extraction, recreation, and shrimp fishing. However, the consequences of the lake's shrinkage extend far beyond the economy. The dry, exposed lakebeds release salty dust into the air, posing health risks to residents in nearby areas. Efforts to address these issues remain crucial not only for ecological restoration but also for the well-being of Utah residents.

Saline lakes worldwide are experiencing similar challenges, with many witnessing declines in water levels due to climate change and unsustainable water management practices. The Great Salt Lake serves as a vivid reminder of the complex balance between economic activity and environmental preservation that rests on humanity's shoulders.
