tpo 18In the 1950s Torreya taxifoha, a type of evergreen tree once very common in the state of Florida, started to die out. No one is sure exactly what caused the decline, but chances are good that if nothing is done, Torreya will soon become extinct. Exp

The reading and lecturer are both about Torreya Taxifoha which population is declining recently. The author of the reading feels that if no step has taken soon Torreya will begin to extinct and presents some solutions to this problem. The lecturer challenged the claim made by the author. He is on the opinion that none of the solutions is satisfactory. To begin with, the argues that to reestablish the Torreya in the region where it used to grow. He claims that Torreya used to grow in the microclimate which is a cooler and wetter place where Torreya will grow easily. The specific argument is challenged by the lecturer. She mentions that maybe Northern Florida is the coolest area when Torreya grew many years ago. But, global warming may increase the temperature and make the microclimate drier than as earlier. Second, The author suggests that to transfer the Torreya in a completely different location. He also states that assist migration will probably help the Torreya to grow more with the help of human by providing a suitable environment. The lecturer rebuts this by mentioning that Black Locus is a tree that moved to the new environment and grows quickly. But, it kills many other plants, thus relocating is not a good idea. Third, the author posits that to preserve seeds and sapling of Torreya plant in the research center and closely monitoring can protect the species from being extinct. In contrast, the lecturer position is that Torreya might survive but genetic diverse will not produce. She also additionally says that the research center will not able to create such an environment.
