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 set of materials, the author strongly postulates that the salinity of lake water is affecting the fish and bird populations and provides three solutions to this problem. On the other hand, the professor states that these solutions are not practical and realistic and provides the drawbacks of each solution.
First and foremost, the passage begins by explaining that the salinity of lake water can be reduced by directly removing water from the lake by a method that leaves behind salts and other chemicals. However, the professor explains that water evaporation leaves toxic substances like selenium that can be spread by wind and people can inhale those substances that can affect their health.
Next, the professor points out that oceans are many kilometers away from lakes and the local government doesn't have the resources to construct the new pipelines and canals because the material for the construction is expensive. These claims refute the author's implication of the construction of pipelines and canals so the water from the ocean can mix up with the lake water.
Ultimately, the article wraps its arguments by explaining the third solution of dividing the lake into sections by constructing walls. However, the speaker in listening refutes this point by showing the inaccuracy of the author that due to geological activities those walls will collapse after sometimes so this solution is not a long-term solution.
