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 lecture, the professor discusses how it would be great to find a soultion to decrease the level of salt in the lake's water, but the mentioned soultions are not practical and have limitions. This cats doubt on the readin which states that these mentioned soultions could be effective in solving the problem.
To begin with, the speaker asserts that using special desalinaton tools would reduce that salt level, but the problem is when water evaporates into steam it leaves toxic matrial. Moreover, such matriales as saluniem could be inhaled by people and causes health problems. This contradicts the text which claims that desalination would be an effective soultion.
In addition, the lecture states that using piplines or canals is not the appropiate soultion. This is because these tools are too expinsive and the goverment can not afford it. Furthemore, the Pacfic ocean is too big and that would requir lots of piplines and canles. This opposes the reading which states that mixing ocean water into the lake woulf decreas the lake's salinity.
Finally, the professor explains why it's unlikely to control lake's salintly by building walls in the long run. In fact, that Salton Sea in Calfornia regulary exposes to intense geological events such as earth quickes. Hence, such event would have collapsed the wall and mix the water back togther. This refutes the passage which states the constructing walls is the right option.
In conclusio, the speaker disagrees with text on all three point and belives that the text lacks credibitly.
