Essay topics:

The Salton Sea in California is actually a salty inland lake. The level of salt in the lake's water—what scientists call its salinity—has been increasing steadily for years because the lake's water is evaporating faster than it is being replaced by rainfall or rivers. If the trend continues, the lake's water will soon become so salty that the lake will be unable to support fish and bird populations. The lake would then become essentially a dead zone. Fortunately, there are several ways to reverse the trend that is threatening the lake's health.
One option is direct removal of salt from the lake's water in special desalination facilities. Water from the lake would be pumped into the facilities and heated. This would cause the water to evaporate into steam, while salt and other materials dissolved in the water would be left behind. The steam would then be cooled down and returned to the lake as salt-free water. Gradually, the high salt levels would be reduced and the lake’s overall health would be restored.
Another possible solution is to dilute the salt level in the lake with water from the ocean. Since water in the Pacific Ocean is 20 percent less salty than water in the lake, bringing ocean water into the lake would decrease the lake’s salinity. The ocean water could be delivered through pipelines or canals.
Yet another solution would be to control the lake's salinity by constructing walls to divide the lake into several sections. In the smaller sections, salinity would be allowed to increase. However, in the main and largest section, salinity would be reduced and controlled by, among other things, directing all the freshwater from small rivers in the area to flow into that main section of the lake.

In the reading passage, the author concentrates on several solutions to reverse the increasing trend in the level of salt in the water of The Salton Sea in California. However, the lecturer casts doubt on these solutions and respectively points out the problems with all the author's assertions.
Firstly, the author argues that direct removal of salt from the lake using desalination methods can solve the problem. By contrast, the lecturer challenges this idea and states that it should be considered that the solid material left behind after the desalination process contains other chemicals as well, like selenium, which is quite toxic. If humans breathe these chemicals, it will be extremely dangerous to them.
Secondly, the author suggests that by adding water from the ocean, which is about 20% less salty, the salt level in the lake can be diluted. Nevertheless, the lecturer brings up the fact that constructing pipelines and canals to deliver the water requires local regulations. Such pipelines over long distances will be so expensive and costly that local governments cannot easily consider this solution.
Lastly, the author asserts that by building walls to break up the lake into several sections, the salinity can be controlled. Conversely, the lecturer refutes this claim too and clarifies that this practice will have short-term consequences since in the case of the next earthquake the walls will be destroyed and as a result, the water with high salinity will be mixed with the water with low salinity. Thus, the whole idea would be ineffective from a long-term perspective.
