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.
题目音频：
In this set of materials, both the reading and the lecture discuse wether or not their is a possible solutions to reduuce salt from Slaton Sea lake. the reading states that there are several ways to reverse the trend that is threarening the laje's health. While the lecture argue this, saying these solutions are not practical according to the folowing argumENT.
First of all, the reading discus the at one solution will be evaporate the water so salts and other materials in the water would be left behind. then, re pump water steam after cooled free from salt to the lake to restore health but the lecture refutes it by mention that not only salt will left behind but also other toxic chemical materials like salmine and will be toxic to air and breath and cause damage to health.
Second, the reading mention that another possible solution by dilute the salt level through delivered pipes and canals from pacific ocean as it contain 20% less salt than the lake to it. the lecture counter this point as construction of such a pipes need from local government to pay a lot especially the distance is almost 100 km and will be so expensive to carry on.
Third, the reading claims that if lake can be control by building several section to divide the lake and the rivers fresh water flow from them into the main section of lake and so on till all other sections.The lecture refutes this point by states that divided wall is a temporary solution and not work in geological activity such as earth quick which will destroy the wall and water will mix again from high section to low one.
