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 passage states that the salinity of Salton Sea can be reduced and controlled and presents some ways for this purpose. However, the professor in lecture casts doubt on the points presented by the reading passage and finds them impractical.
First, considering the reading passage the salt can be removed from the lake's water using facilities which decalinate the water by boiling it at first,separating its salts and chemicals and then cooling it down again. In contrast, the professor in the lecture contradicts the idea and further explains that other chemicals which are removed from water such as Selenium can be dangerous for human life if the wind carry it in the air.
Second, the reading claimes that water from ocean can be tranferred to mix up with the lake's water and reduce its salinity. On the contrary, the professor in the lecture refutes the information presented in the reading passage and makes the point that constructing pipelines or canals for transferring water over 100 kilometers from the ocean can be extremely expensive and requires resources which maybe the local government can not provide.
Third, the author in the reading passage puts forward the idea that walls can be build in the river to devide it into sections. Smaller sections will get saltier but the salinity of the major sections will be reduced and controlled by making the fresh water flew into the major section. On the other hand, the speaker in the lecture contradicts the idea and add that those walls will not work for longtime since geological occurances such as earthquackes may destroy it and then water in the sections will mix up which increases the salinity.
