## Quick Overview

The Great Salt Lake is facing imminent collapse, predicted by researchers to potentially vanish within five years by 2028, due to human water consumption and climate change, which threatens the region's entire ecosystem, economy (including skiing and brine shrimp industries), and the health of millions living along the Wasatch Front due to toxic dust storms.

**Key Points:**
- Researchers from Brigham Young University warned in early January 2023 that the Great Salt Lake could completely disappear within five years, by 2028.
- The lake has already shrunk by 51% between 1986 and 2021, leaving behind 900 square miles of toxic, arsenic-laced lakebed exposed.
- The primary cause of the lake's decline is human water consumption, with agriculture consuming 74% of the water supply in the Wasatch Front region, which contains over 2.8 million people.
- The sustainable withdrawal rate for the lake's watershed is 1.1 Million Acre-feet (MAF) annually, but total consumptive use is 2.3 MAF annually, resulting in a 1.2 MAF annual water deficit.
- The shrinking lake threatens the region's economy, including the ski industry (due to reduced lake-effect snow) and the brine shrimp industry (which provides 40% of the global brine shrimp feed source).
- The exposed lakebed contains high amounts of toxic materials like arsenic, lead, mercury, and antimony, which are increasingly being blown across the region as dust storms, threatening public health.
- The loss of the lake is projected to cost the state of Utah over $2 billion in lost economic activity and jobs, including those in the dairy and beef industries, which rely on the lake's ecosystem.

**Context:** The video addresses the severe water crisis affecting the Great Salt Lake in Utah, the largest saline lake in the Western Hemisphere. It contrasts the lake's historical size (Lake Bonneville, 17,000 years ago) with its current critically low levels, highlighting the human and climate factors accelerating its decline and the resulting ecological and economic crises facing the densely populated Wasatch Front region.

## Detailed Analysis

The video warns that the Great Salt Lake is rapidly shrinking, with researchers predicting its potential complete disappearance by 2028 if current trends continue. Since 1986, the lake has lost 51% of its surface area, exposing vast areas of toxic lakebed containing arsenic, lead, mercury, and antimony. This toxic dust pollution is already impacting air quality in the Wasatch Front region, home to over 2.8 million people in cities like Ogden, Salt Lake City, and Provo. The primary driver of this crisis is human water use; the sustainable withdrawal rate for the watershed is 1.1 MAF annually, but total consumptive use is 2.3 MAF annually, creating a 1.2 MAF annual deficit. Agriculture accounts for the vast majority (74%) of this consumption, while mineral extraction and cities/industry each account for 9%. The lake's decline also severely impacts the local economy, threatening the ski industry due to reduced lake-effect snow and the vital brine shrimp industry, which supplies 40% of the world's brine shrimp feed. The overall environmental catastrophe is projected to cost Utah billions in economic losses and threaten public health from dust storms affecting neighboring states as well. The video contrasts the current arid state with historical images of the lake and the thriving historical settlements along the Wasatch Front, emphasizing the severity of the current crisis.

### Great Salt Lake Decline (1986-2021)

- Lake shrank by 51% in surface area
- Exposed lakebed contains toxic minerals like arsenic, lead, and mercury
- Evaporation accounts for 2.3 MAF loss out of the lake annually.

### Water Imbalance

- Sustainable withdrawal rate is 1.1 MAF annually, but total consumptive use is 2.3 MAF annually
- Resulting in an annual water deficit of 1.2 MAF.

### Water Use Breakdown (Total 2.3 MAF Consumed)

- Agriculture uses 74%
- Mineral Extraction uses 9%
- Cities & Industry use 9%
- Reservoir Loss/Inefficiencies account for 8%.

### Regional Impacts

- Toxic dust storms threaten the health of millions on the Wasatch Front (Ogden, Salt Lake City, Provo)
- Economic damage estimated at billions, threatening ski and brine shrimp industries.

### Historical Context

- The Great Salt Lake is the modern remnant of the much larger Lake Bonneville (17,000 years ago)
- Owens Lake is presented as a parallel ecological disaster due to water diversion.
