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 listening content totally refutes the reading passage in the several ways to reverse the trend that is dangerous to the lake's health. To begin with, the reading says that there is an option that we can directly remove the salt from the lake's water in special desalination facilities. However, the speaker argues that even it is true that it would reduce the salt level of lake, but it would make the serious problem. When salt and other materials dissolved in the water during the water to evaporate into steam, it would generate some toxic chemical material which would increase health risk. For example, if this type of chemical material release into the air, it would exacerbate the air. People who live near the facility would be dangerous if they breath.
Moreover, the reading suggests that diluting the salt level in the lake with the water from the ocean can reduce the lake's salinity. The listening points out the fact that the government would not have enough resource to make this happen. If we want to dilute the salt level of the lake by the water of the ocean, we need to build the pile which is about 100 kilometer long. This construction is too expensive that the government cannot accomplish.
Finally, the reading thinks that we can construct walls to divide the lake into several sections. Nevertheless, the speaker asserts that the location of those walls is too dangerous so that this solution is impossible. This lake is near the California which is the various geological place. There are lots of earthquakes happened everyday. If we construct walls there, the walls will collide each other and destroyed by the earthquakes. The salt lever would not be able to divide successfully.
