The passage talks about the problem about the decrease of Torreya taxifoha, and gives three solutions to it. In the lecture the professor disagrees with all the methods that provides in the reading passage. Instead, she point out that the possibility of achieving the ultimate goal is faint.
To begin with, in resolving the problem, the option is to rebuild the Torreya in the location where they used to be established. However, the professor would like to claim that due to the global warming, the expected effect wouldn’t be appeared. On the contrary, the climate in the northern part of Florida, which is very not too dry or hot, is now quite drier than that before.
Secondly, the passage provides another option is that Torreya could immigrate to an entirely new habitat, which is very far from the Florida microclimate. Does it work? Definitely, no! Based on the examples that side effect of immigrating balck noka tree, if Torreya change its location to the totally different one, it would hold the potential problem whether or not this action will do harm to the environment of the new location.
Finally, it’s obvious that the passage holds a seemingly unbelievable solution that preserves the Torreya in reaserch center. The speaker gives her reasons that the situation is not suitable for plant to survive. Not only do the decrease of the capability to disease, but also the capacity of the research center is not enough to keep a large amount of Torreya. Thus, the way to protect Torreya from extinction is unconvincing.
In all, the professor disagrees with the methods provided in the reading passage.
