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.
Both the author and the lecturer discuss feasibility of removal of salt from the Salton Sea in California. The passage claims that there are several solutions to reverse the trend that is threatening the lake's health. The professor, on the other hand, completely rejects whatever mentioned in the reading through citing three reasons.
First, both the author and the professor talk about desalination facilities. According to the passage, the high salt levels would be reduced by desalination facilities and the lake's overall health would be restored. The lecturer, nevertheless, rejects author's view and illustrates the idea that desalination causes serious problems. desalination facilities increase health risk because some solids remaining left behind are toxic such as selenium. In other words, people are faced by breath problems when they breathe some air.
Secondly, both the reading and the lecture discuss diluting approach. The passage argues that bringing ocean water into the lake would decrease the lake's salinity. However, the professor refutes this, saying that the ocean water could be delivered through pipelines or canals which impose a great deal of expense to government. some pipelines' length is about one kilometer, so constructing pipeline is very expensive.
Eventually, both the passage and lecture address the subject of constructing wall. The passage goes on to mention that constructing walls would control the lake's salinity. In contrast, the lecturer points outs that some disasters such as earthquake destroy walls. The wall would collapse after a while and salty water will be mixed with fresh one again.
