The lecturer expresses her negative attitude toward the three options mentioned in the reading passages which are focus on helping Torreya survive in Northern Florida.
The first option is to rebuild(paraphrase,好!) the Torreya in original area. However, the lecturer objects it because it is unlikely to succeed. The lecturer mentions that the microenviornment has already changed because of(because) the larger climate is differential, possibly due to either the global warming or the local drying out.
The second option suggests that move Torreya to another location(不是一句句子哦). Nevertheless, the lecturer go(goes) against this idea by giving the outcome from another real case, the migration of Black Nocers. She says that the Black Nocers were so quickly spread that they kill a lot of originated trees, some of which were already endangered, making them distinct. The unexpected outcome appears because of the unbalance of the ecosystem.
The third option is to preserve Torreya in research centers. Nonetheless, the lecturer opposes that to resist a species for seasons(什么意思?求讨论!!!), genetical diversity should be assured. Due to the large size of Torreya, there are no capacity to preserve a large amount of Torreya in the research centers and therefore, the option cannot preserve the Torreya to survive in a long term.
