The reading passage’s author claims that
there are certain ways which can cope with the lake’s salinity. She suggests
three possible ways, however, the professor in the lecture argues that they are
not realistic, and not practical.
To begin with, the professor insists that
there could be serious health problems if the lake’s salinity is controlled by
desalination facilities. This is because when the lake’s water would be pumped
into the facilities and evaporated, some solid materials and salt would remain.
However, not salt, but other types of a chemical such as selenium can threaten
people’s health if the wind spread and transport it throughout the town. This
casts doubt on the reading passage’s claim that salt from the lake’s water can
be desalinated through facilities.
Furthermore, the professor suggests that
constructing pipelines or canals to dilute the salt is not applicable.
Constructing pipelines or canals hundreds of kilometers away will require a tremendous amount of money, which is not affordable for the government.
Therefore, this suggestion is not viable. This contradicts the reading
passage’s claim that the salt level in the lake can be diluted with ocean water
by building pipelines or canals.
Finally, the professor contends that
constructing walls is just a short-while solution because there is frequent and
intense geological activity. Therefore, this geological turmoil or earthquake
can destroy the walls, then will make the water of high salinity will be mixed
back into the water of low salinity. Hence, this is unlikely to work as a
scenario. This refutes the reading passage’s claim that constructing walls to
divide the lake into several sections can help to regulate the lake’s salinity. |
