TPO-54 Summarize the points made in the lecture, being sure to explain how they respond to the specific concerns 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 lecture and the reading are about salinity of Salton sea. The reading states different measures to reduce the salinity of the lake. However, the lecturer casts doubt on what is presented in the text and refutes all the methods given in the reading. She does not feel that these methods are as beneficial as the author assumes.
First of all, the lecture argues that desalination facilities may reduce the salinity of the lake, but when the water will evaporate, it will leave behind some solid materials. These solid materials when mix up with other types of chemicals like Salanium will make the air toxic. Therefore, when people breath them in it can cause severe health risky to them.
Secondly, with regard to the third method, dilution of lave with ocean water, the lecturer explains that this method would require construction of pipe lines or canals to bring the water. The ocean water would be around hundred kilometers away from the lake, hence the construction cost will be very high, and the government can not spend such humungous amount of money on the project. The reading passage gives the opposite view. Ocean water which is only 20 percent salty, when mix up with saline water will reduce the lake salinity.
Finally, the lecturer objects to the third measure - construction of walls to divide lake into various sections. She points out that this method is unlikely to sustain very long. Sometimes intense activities like earthquake may occur in the areas, which can break the walls and ultimately the high salinity water will mix back in with low salinity water in the main section. This is in direct contradiction with the claim in the reading passage that this measure can reduce and control the amount of salt in the lake.
