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 writer claims in the passage that there are several ways of reducing the salnity of the Salton Sea in California, but the professor argues in the lecture that these ideas are not realistic.
First, the author presents a viewpoint that direct removal of salt from the lake's water in special desalination facilities by heating and evaporating of water is one way. However, the listening puts forward a different opinion that the toxical material in the water may be evaporated to the air. And when people are breathing the air cotains toxical material, it's bad for their health.
Second, the reading states that the government could import the water from ocean to the lake. This is ecause the water in the Pacific Ocean is 20 percent less salty than water in the lake. While the lecturer argue that the pipline is too expensive to buy by the government, because the distance form ocean to the lake is about 100 kilometers.
Third, the reading claims that the lake could be devided into several parts in order to decrease to salnity of main parts with the risen of salnity in small parts. While the profesor contends that the division of the lake could just constant in a short time. This is because there are many geology activities like earthquakes which can ruin these division.
