Essay topics:

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 material and the lecturer are both about reserving the trend that the salt leverl of the Salton Sea will keep increasing. The author suggests three solutions, but the professor mentions that none of these are realistic.

First of all, the professor rebuts the point made by the author that salt can be removed directly by heating the water from the lake in the facilities and leaving salt and other materials behind. She points out that these materials contain chemicals which are toxic. These chemicals may be also evaporated into the steam can be exposed to poeple, whcih is really dangerous. For example, if people breath in such chemicals, there health is threatened.

In addition, while the author argues that since the salt level of ocean water is 20 percent lower than water in this lake, ocean water can be introduced to decrease the lake's salinity. However, the lecturer contradicts that if ocean water is used, the goverment needs to construct pipe lines about 100 kilometer long. Since pipes are expensive, the goverment may not have enough resources to pay for them.

Finally, the reading material proposes that walls can be applied to divide the lake into several sections. For smaller sections, salinity would increase but for the main and largest section, salinity is reduced with freshwater directed from small rivers in this area. However, the professor casts doubt on this idea. She explains that these walls will not work for a long time. Since there are intensive geological activities, like earthquakes, walls are likely to be destroyed and the collapse. At that time, water with high level of salt will mix with water of lower salinity, which means that this method is not plausible.
