    The Salton Sea in California – Summarize the points made in the lecture, being sure to explain how they respond to the specific concerns presented in the reading passage.

    The Slaton Sea in California is facing a problem that the salinity is continuously increasing, and the reading passage has proposed three solutions. However, the professor in the lecture does not agree with the idea that the given solutions are realistic and practical.

    Firstly, it is said that desalination facilities can be used to directly remove the salt from the lake by using pumps and sending cooled water backed to the lake. Although the professor agrees that this method can decrease the salinity of the lake, she points out that serious problems can be induced by doing so. More specifically, the solid materials left behind after evaporation can pose a potential health threat. If the toxic chemicals are swept by the wind into the air, people may breathe it into their lumps, which can be very harmful to their health.

    Secondly, diluting salt level with the water from the ocean is proposed to be a valid solution. Even though the professor agrees that it may help solve the salinity problem, she argues that this solution requires pipes to be constructed, and the local government may not have the resources to pay them. She thinks this can be a significant problem since these pipes can be very long and need lots of piping materials. As a result, the cost of constructing such pipes can be very expensive.

    Moreover, it is proposed that building walls to divide lakes into several sections and using the freshwater from small reivers to reduce the salinity of large sections can also solve the salinity problem. Nevertheless, the professor does not believe it can work for a long time. When earthquakes take place, these walls can easily collapse, and the freshwater will mix back to the small rivers.

    In general, the professor thinks that the three proposed solutions are impractical and unrealistic based on the reasons mentioned above.

    The Slaton Sea in California is facing a problem that the salinity is continuously increasing, and the reading passage has proposed three solutions. However, the professor disagrees with the idea that the given solutions are realistic and practical.

    To begin with, according to the reading passage, desalination facilities can remove the salt from the lake by using pumps and sending cooled water back to the lake. Although the professor agrees that it can decrease the salinity of the lake, she points out that serious problems can arise by doing so. More specifically, the solid materials left behind after evaporation can pose a potential health threat. If the wind sweeps some of these toxic chemicals into the air, and people breathe them in, it will be very harmful to their health.

    Besides, diluting salt level with the water from the ocean is said to be a valid solution. Even though the professor agrees that it may help solve the salinity problem, she does not think it is a viable solution in reality. The main reason is that this method requires constructing pipes, and the local government may not have the resources to pay them. She argues that this can be a significant problem, given that these pipes can be very long and need lots of piping materials. As a result, the cost of constructing such pipes can be very expensive.

    Moreover, the reading passage proposes to build walls to divide lakes into several sections and use the freshwater from small rivers to reduce the salinity of the large sections. Yet, the professor does not believe it can work for a long time. When earthquakes occur, these walls may collapse, and the freshwater will mix back to the small rivers.

    In general, the professor thinks the three proposed solutions are impractical and unrealistic because of the reasons mentioned above.
