Question:Summarize the points made in the lecture, being sure to explain how they respond to the specific concerns presented in the reading passage. The reading explores three ways to alleviate the salinity of the Salton Sea. The professor in the lecture thinks that there are several problems about these methods, which contradicts what the reading states. In the lecture, the professor uses three points to support his ideas.

Firstly, even though the reading believes that people can remove the salt by evaporating the water to reduce the high salt levels, the professor contends that it may still leave other toxic chemical materials. When the toxic materials evaporate into the air, people are likely to breath them, which damages the people\\\'s health.

Moreover, despite the statement in the reading that people can construct the pipelines or canals to dilute the salt level in the lake with water from the ocean, the professor in the lecture argues that the government cannot afford it. The ocean is far away from the lake, which is about 100 kilometers away. The government has no reason to pay for the huge bill.

Finally, the professor asserts that the wall built in the lake will easily damage by the geography activities, whereas the reading claims that the separated walls can help lower the salinity. If there is an earthquake in the lake, the walls would break down, which means they cannot divide the lake into seral sections and the lake in the smaller areas would finally flow into the main section of the lake, which causes  the enhancement of the salinity of the lake.
