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 reading and the lecture are both about the Salton sea in california is facing a problem that the salinity has been increasing for the rapid evaporation rate and provides three reasons of support. However, the professor explains that is agreat idea if we could stop the lake salt level from increasing and save its fish and bird populations and refutes each of the author's reasons.
In the first place, the reading claims that one option is direct removal of salt from the lake's water in special desalination facilities. The professor refutes this point by saying that as the water pumped into desalination facilities evaporates, solid materials that desalination facilities left behind which contain toxic chemical, such as selenium. And then, separating would allow these chemicals to be spread by wind, which may pose a threat to people’s health.
Second, the article posits that the another possible solution is to dilute the salt level in the lake with water from the ocean. However, the professor says that it would require constructing pipelines or canals. The problem is that the local government may not have enough resources to pay for such major construction. the nearest shoreline of the Pacific Ocean is 100 kilometers away. Pipelines and canals are very expensive to build over such long distances.
Third, the reading says that the last way 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. 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. However, the professor refutes that this measure is just provisional, since the Salton Seas is located in place where the geological activities are frequent and intense. Water from the smaller sections may mix back in the main section so this solution will also fail very soon.
