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 reading passage and the lecturer discuss the posible solution to halt the salinity of the Salton Sea in California. While the reading passage brings up three redemies to stop the salinity, the lecturer finds them impractical and provides some evidence to refute them.
First, the writer argues that by some processes, salt can be removed from the lake. These process done with special desalination facilities in which the water will be evaporated. After the salt remain from this process, the steam would be cooled down and back to the lake. On the other hand, the professor asserts that this process has some severe problems. Other toxic substances in the water would be remain besides the salt. Afterward winds can circulate them in the air and these would be harmful for surrrounding people.
Second, the author declares that the local government can brings ocean water to the lake by constructing pipelines. The ocean water have little salt rather that the lake, so it can be a solution. Conversely, the professor states that construction of pipeline is not be logical and affordable for the government. The mentioned pipelines should have more than thousands kilometer length. Consequently it would not seem functional.
Finally, the writer says that the salinity process can be stoped by dividing the lake in seperate parts by some specific walls. Then the major part would been fresh through flowing small rivers in it. So its salt would be reduced and controled. But the salinity will be continued in small parts. The lecturer asserts that the wall will be ruined by earthquake.
