Summarize the points made in the lecture, being sure to explain how they challenge the specific arguments presented in the reading passage.
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 article suggests three ways to reduce the salinity of the Salton Sea. However the professor from the lecture stands against to these proposals. She thinks that these suggestions are either not practical or too dangerous to conduct.
First, the article states that we could extract the salt by vaporizing the water in the Salton Sea. Unfortunately, the professor points out that the remaining of the extraction process could be poisonous. There are various chemicals aside from salt dissolved in the water. The evaporation process not only produces salt, but also produces other chemical that would harm people's lives. If these particles are blown to the residential area nearby, there will be tremendous damage to inicent people.
Secondly, the author states that pumping sea water into the lake and dilute the lake water could be a way to lower the salt level. However, the professor doesn't believe this plan being practical. Since pumps are expensive and the distant to the nearest sea is considerably long, she predicts that the expense would not be affordable to the local government.
Last, the writing provided that we could divide the lake into sections. Salinity would be reduced and controlled in the main section. The professor holds her concern that this might not be a long tern solution. There is constant geological activity in that area. Hence, the division construction would be destroyed in any time.
