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.
In the reading passage, the author mentions that the Salton Sea in California is a salty inland lake and the level of salt in the lake's water has been rised for years, which will influence the bird population and come up with three solutions for this problem. However, the speaker in the lecture thinks these three solutions are not pratical and rebuts these ideas one by one.
Firstly, the author of the reading passage thinks that removing the salt from the lake's water by desalination facilities. But the lecturer refutes this point. She maintains that this method will bring some problems. For example, if the salt is pumped out from the lake, it will leave some materials. Some of the materials are toxic chemicals and if the wind brings them into the air, it is harmful for people's health.
Secondly, according to the reading, the salt level in the lake can be diluted by the ocean water. Nevertheless, the lecturer disputes this idea. And she asserts that in order to reduce the salt level in the lake, it would need pipelines and canals. However, the distance between the lake and construction site is so farther that it would be expensive to build these pipelines. And the local government is not able to pay for the bill.
Finally, in the reading passage, the author believes that constructing walls to divide the lake into several parts can control the lake's salinity. On the other hand, the speaker thinks that is is not likely to reduce the salt level by doing this. Because the region is likely to have earthquakes and that would tear down those walls, which will let the salt water back into the main region.
