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 passage proposes three plans to prevent the Salton lake from becoming a dead zone, which is an area of very high salinity that is no longer able to support any kind of fish or birds. However, the lecturer casts doubt on the solutions suggested in the article. She mentions that the proposals are unrealistic and impractical.

First of all, the author claims that the salt level in the lake could be decreased by using desalination facilities, which work by heating water to convert it to steam leaving behind any salt or other minerals as a deposit. The steam could then be cooled down and returned to the lake as water free of salt. The lecturer, on the other hand, challenges this idea. She argues that this will help reduce the salinity but will also cause serious problems. She elaborates that the residue left after water evaporation is not only salt but also contains other minerals. One of those minerals is selenium, which could pose a major health risk. According to the lecturer, the wind could carry selenium into the air, which would further be breathed in by some people and this would be dangerous to their health.

Second, the author believes that this problem could be solved by constructing pipelines and canals to let less salty water from the ocean flow into the lake. Nonetheless, the lecturer holds that this would be too costly for the local government, especially that the nearest shoreline to the lake is a hundred kilometers away.

Finally, the writer assumes that building walls to divide the lake into sections could help resolve this issue. In contrast, the lecturer points out that the region is known for geological instability and earthquakes. She explains that although erecting these walls could have a short-term benefits but they would collapse on the long-term due to the shaking as a result of earthquakes.
