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 suggests several ideas which lead to the Salton Sea's salinity control. The lecturer, however, finds the idea dubious and casts doubt on the suggestions proposed by the reading passage.
The author argues that salt can be reduced by the desalination's process. The water evaporates, and the salt remains solid. Then, the steam will cool and return to the lake as water. Conversely, the lecturer brings up the idea that although it might help to decrease the lakes's salinity, it will cause health issues. Besides salt, there are some chemicals in the lake's water. When the water evaporates, solid materials which contain salt and toxic chemicals will disperse in the air, and breathing these toxic chemicals will cause health problems.
Furthermore, the reading passage holds the view that by diluting the lake's water with the ocean's water, salinity will reduce. On the contrary, the speaker underlines the fact that this idea requires pump lines and channel construction, and these constructions cost a lot. The distance between the lake and the ocean is about 1000 km. Building a 1000 km long channel is too expensive.
Finally, the reading asserts that dividing the lake into sections by constructing walls might be helpful. In contrast, the speaker dismisses this issue due to the fact that the lake is placed in a region with intense geological activities. Earthquakes happen there consistently. So, the walls can not remain for a long time, and they will destroy when an earthquake happens. After the wall's destruction, salty water will mix with the main section's water.
