Both the reading and the lecture are talking about the procedures than could be used to save the fish in Salton Sea in California. The reading part supports the idea that there are several ways to solve this issues. On the other hand, the lecture opposes this opportunity.
First, the passage supports the idea that removing the salt from the lakes' water in special desalination facilities, where the water will be pumped and heated. In this way the water will evaporate into steam and the salt and other materials will be left behind, and the water that will be returned into the sea will be less salty. However, the lecture disagrees with this, because it says when the water will evaporate it will leave behind other chemical materials that could be unhealthy and toxic for the people. For example, said the selenium is toxic and the people can breathe it and it is very danger.
Another possible way to reduce the salt from the water given from the reading part is to dilute the salt level in the lake with water from the ocean. But the listening part opposes this, by saying that this method is very expensive and the local government will not have the sources to pay for that construction.
Finally, the author gives one more option, to control the lake's salinity by building walls to divide the lake into several areas. In contrast, the lecturer says this method is unlikely to work for so long. She says that there are earthquakes that can destroy the wall and the water from different sections will mix in.
