In the lecture, the speaker presents a comprehensive rebuttal to the reading passage's suggested strategies for mitigating the rising salinity in California's Salton Sea. Although the reading passage enumerates three potential solutions, the lecturer provides compelling evidence that these proposals are flawed and may not be feasible.
The first solution offered by the reading passage proposes the utilization of desalination facilities for direct salt removal from the lake. While this strategy might ostensibly appear to be a promising approach, the lecturer refutes it by elucidating the significant health risks that come with the operation of desalination plants. The solid materials left behind by desalination are not only composed of salt but also incorporate other chemicals, including toxic substances like selenium. If these are released into the air and subsequently inhaled by humans, the public health repercussions could be substantial.
The second proposed solution in the reading passage involves using seawater to dilute the lake's salinity. While the lecturer concedes that this could reduce salinity, he points out the financial implications. Given that the nearest Pacific Ocean shoreline is 100 kilometers away, constructing pipelines or canals for the water transfer would demand a vast amount of resources, which could be prohibitive for local government budgets.
Finally, the reading passage suggests controlling the lake's salinity by partitioning the lake into different sections. However, the lecturer posits that this plan is unlikely to be successful due to the region's significant geological activity. The prevalence of earthquakes could lead to the destruction of the dividing walls, causing the sections with higher salinity to mix with the main, lower-salinity section, and making this solution only temporary.
