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 professor in the lecture does not agree with the ways to decrease salt level in The Salton Sea in California that provided by the reading, The professor tries to persuade his class that all these three solutions are unrealistic and not practical.
First, Regarding Using special desalination facilities, The lecture avers that this facilities will leave behind solid materials.These solid materials contain some chemical toxic materials. So, If wind spread these toxic materials in air, People will breath them. Therefore, It will increase health risks. This point directly refutes the point from the reading which states that we can use desalination facilities to remove salt from lake's water directly.
Second, According to dilution using ocean water, The speakers asserts that to deliver water from ocean, We need a lot of constructions but the local government does not have enough money. The shore line is 100 kilometers so, it is very expensive to build. Again, this point contradict the point from the passage which claims that the ocean water could be delivered through pipelines or canals.
Third, according to dividing the lake into several sections, The professor argues that this solution will not work for very long time. She says that the lake can face earth activities like earthquake. These earth activity could collapse the walls so, the water will go from special sections to main section. So, this point casts doubt the point from the reading because the reading says that we can construct walls to divide the lake into several sections. Therefore the small sections will have water with high salinity while the big section will have less salinity.
