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 states that there are three approachs which help them to reduce the salinaty of the lake and preserve its health. The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
The author argues that by using the desalination technology and entering back the water without salt and other material to the lake, they can decline its salinaty. Conversely, the lecturer brings up the idea that this procedure brings about health problems for people. Beacause the remained solid material through this method may consists of some toxic chemicals such as selenium which its presence in the atmosphere puts people in danger.
Furthermore, the reading passage holds the view that bringing fresh water from ocean through pipelines and cannals can dilute the water in lake and reduce the percentage of salt it contained. On the contrary, the professor underlines the fact that the government may not have resources to support this project financially. Although providing fresh water from long distances can be a good course of action, it costs expensive.
Finally, the reading states that dividing the lake into several parts by creating walls and leading rivers into the main large part can be useful to reduce the amount of salt generally. In contrast, the speaker dismisses this issue due to the fact that this method will not be beneficial for long-term. In case of an earthquake the built walls may destroy and all parts combine together again. As a result, the whole lake will suffer from the high level of salt.
