▶ Your Answer :
Both the lecturer and the writer are
discussing about the three ways of protecting Torreya. The writer claims that
reestablishing Torreya in the same location, moving it to an entirely different
location, or preserving it in research centers as the ways to avoid its
extinction. However, the lecturer casts doubt on these methods by giving
counterarguments.
To begin with, the lecturer explains that
reestablishing Torreya in the same location cannot be a good method, because
the climate of the area is changed. Northern Florida, the area in which Torreya
used to be found in abundance due to its favorable weather, is not coolest,
dampest region any more. In other words, there cannot be expected prosperity of
Torreya as past days. This goes against the reading passage’s idea that
establishing Torreya in the same location again by planting its seeds will be
the way of avoiding extinction.
Moreover, the lecturer insists that moving
Torreya to other area is not plausible. The lecturer cites one example about
similar situation happened to Black locus the tree. Black locus once confronted
the crisis of extinction. So humans altered its habitat to North. It spread so
quickly and rather it killed of many plants as well as other species of trees
in the new environment. This unpredicted outcome refutes the reading passage’s
claim of opinion of moving Torreya to other region.
Finally, the lecturer argues that
conserving Torreya in research centers is impractical method to protect it.
According to the lecturer, to prevent it from disease, their habitat must be
relatively large and genetically diverse. However, it is not practical to
reproduce the center’s environment to satisfy those requirements. This counters
the reading passage’s argument: preserving Torreya in research centers will
help surviving of Torreya because scientists in research centers can get more
chances to study it and will be more likely to make solution to stop the extinction
crisis.
