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.
Both reading and speaking focus on the solution of reducing salinity, but express opposing viewpoints. Whereas the author provide three options to solve this problem, the professor disagree with the authors' solutions for the following reasons.
To begin with, according to the text, the author mentions that one solution is to pump the water from lake into the facilities. On the other hand, the speaker states that salt and other materials dissolved that left behind can damage to people and animal in that area. This is because the solid materials that left behind is toxic chemical.
In addition, based on the text, another way to solve this problem is to dilute the salt level in the lake with water from the ocean. On the contrary, the professor said that the ocean is 100 kilometers far away from the lake. The government have to spend a plenty of money.
Lastly, the writer says that another options is to construct walls to divide the lake. In contrast, the speaker states that California is located in the region that usually have earthquake. In short term, this solution might be work but the wall would be damaged from disaster in the future. As the result, the water will mix back to the main section.
