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.
The reading asserts that the water of the Salton Sea in California is becoming more and saltier because of water evaporation, leading to problems for birds and animals population. The passage suggests three main solutions to face the problem. The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
To start with, the author argues that one fine choice would be to extract all the salt from the water by transferring it into facilities for desalination, so by heating it make the salt remain separated. Then the vapor could be cooled and sent back to the lake. Conversely, the speaker brings up the fact that it is not a practical approach to solve the problem: she maintains that the remained salt and other materials could cause health threats for human. some toxic material will mix in the air and cause damage to man's lives.
Furthermore, the passage holds the view that the salty water of the lake could be diluted by transporting less salt-contained water from the Pacific ocean via pipelines or canals. In contrast, the lecturer underlines the fact that although ocean water can solve the problem, there are limitations in resources to construct such infrastructures by governments. Since the distance between ocean and the kale is about 1000 kilometers, it is unlikely to be possible to build the canals.
Finally, it is stated in the passage that another solution for this problem could be to make some system of walls, and make different zones in the lake. In this way, the small parts will salinity will increase, but in the main and large parts, the salinity would decline and be under control. Additionally, freshwater could be added to the main part from small rivers, and prevent the high level of salinity in the lake. On the contrary, the lecturer dismisses this issue due to the fact that geological conditions in the area are not stable. For instance, there are frequent earthquakes there and one move of them could destroy the walls and all parts will fall apart and separated water will mix again.
