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 and the lecture are both about possible measure to reduce salinity of the Salton sea. The author provides three ways to reduce salinity of the sea. However, the lecturer says it as impractical and non convincing by providing three compelling reasons.
First of all, according to the reading, salt can be removed from the sea by desalination facilities. The lecturer agrees that it indeed removes the salt from the water, but it creates more health hazard to the people. beside salt,the solid waste dissolve in the water may contain toxic element like selenium if it breathe by the people, they may suffer serious health consequence.
Secondly, the author purposed that diluting water of the lake by the ocean can reduce salinity of the lake. it requires build of the canals to take water from the pacific ocean to the lake. Even this concept is real, the lecturer says to build the canal is far more costly that could not bear by the authority due to less resource.
Lastly, the lecturer view the idea of constructing wall to reduce salinity of lake is true but impossible to carry out. The geological force like earthquake may break the wall between lake that might mix up the all the concentration of the lake water. this negates the claim of the author that it may reduce the lake's salinity.
In conclusion, the lecturer refutes all the argument made in the passage by providing logical explanation.
