SOS: The Salton Sea Walk is an environmental documentary that draws attention to the urgent crisis surrounding the Salton Sea, California's largest body of water. The narrative unfolds through the lens of Randy Brown, a dedicated advocate for the Salton Sea's restoration, as he embarks on a physically and mentally demanding walk around the almost hundred-mile perimeter of the sea during the peak summer season to raise public awareness. The documentary presents the intricate history of the Salton Sea, exploring its unintentional creation in 1905, its peak as a popular vacation spot in the mid-20th century, and its ensuing deterioration primarily due to complex water management issues. The reduction in the Colorado River's inflow, which once nourished the sea, has led to escalating salinity levels, threatening the survival of its unique ecosystem. The shrinking of the Salton Sea has exposed extensive playa areas, resulting in toxic dust storms that pose severe health risks to surrounding communities by escalating asthma and other respiratory conditions. Economic implications, including property value depreciation, job loss, and impact on local agriculture, are also highlighted. The film interweaves Randy's challenging journey with insightful interviews from a variety of experts such as scientists, environmentalists, and local officials, all emphasizing the urgent need for intervention. Various restoration proposals are discussed, with the standout being the ambitious "Sea to Sea” project, which proposes channeling water from the nearby Sea of Cortez to replenish the receding Salton Sea. "SOS: The Salton Sea Walk" advocates for a multi-faceted approach to the restoration process, encompassing not only the immediate environmental needs but also creating job opportunities, advancing renewable energy projects, and revitalizing the regional economy. While the Salton Sea's situation remains critical, the film concludes with a hopeful message, urging collective action, increased public awareness, and policy changes to rejuvenate the Salton Sea and avert a potential ecological disaster. It is a potent reminder of the interconnectedness of humans and the environment, and the shared responsibility we hold in conserving and restoring our natural world.
