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.
Summarize the points made in the lecture, being sure to explain how they respond to the specific concerns presented in the reading passage.
The reading suggests several ways to reduce the salinity of the lake and provides three reasons for support. However, the professor says that the methods are unrealistic and impractical and refutes the author's reason.
First, the reading claims that desalination would be an option for the direct removal of salt from the lake's water. The professor opposes this suggestion by saying that in the desalination process salt and other materials would be left behind and this salt would be a health risk. He also states that there would be other materials that can be toxic and can spread into the air. People will breathe these harmful materials into their bodies.
Second, the reading posits that bringing ocean water into the lake would decrease the lake's salinity. However, the professor mentions that it requires a large pipeline. He states that the city does have not enough resources to spend money on this 100km long pipeline.
Third, the reading says that constructing walls to divide the lake into several sections would be another solution. However, the professor refutes this point by explaining that earthquakes can destroy the walls. We also learn that after destroying walls, the water of high salty will mix with the low salty water.
