In the 1950s Torreya taxifolia, 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. Experts are considering three ways to address the decline of Torreya.
The first option is to reestablish Torreya in the same location in which it thrived for thousands of years. Torreya used to be found in abundance in the northern part of Florida, which has a specific microclimate. A microclimate exists when weather conditions inside a relatively small area differ from the region of which that area is a part. Northern Florida's microclimate is very favorable to Torreya's growth. This microclimate is wetter and cooler than the surrounding region's relatively dry, warm climate. Scientists have been working to plant Torreya seeds in the coolest, dampest areas of the microclimate.
The second option is to move Torreya to an entirely different location, far from its Florida microclimate. Torreya seeds and saplings have been successfully planted and grown in forests further north, where the temperature is significantly cooler. Some scientists believe that Torreya probably thrived in areas much further north in the distant past, so by relocating it now, in a process known as assisted migration, humans would simply be helping Torreya return to an environment that is more suited to its survival.
The third option is to preserve Torreya in research centers. Seeds and saplings can be moved from the wild and preserved in a closely monitored environment where it will be easier for scientists both to protect the species and to conduct research on Torreya. This research can then be used to ensure the continued survival of the species.
In the lecture, the professor casts doubt on three methods provided in the reading passage to protect the torreya taxifoha trees. The professor asserts that none of them provide the satisfactory solution.
Firstly, contrary to the belief in the reading passage that reestablishing in the same location in the northern part of Florida, where torreya has thrived for thousands of years could assure the species stay in the familiar microclimate, which is wetter and cooler than surrounding area. The professor asserts that climate changing, especially the global warming, has altered the local microclimate to become dryer(drainage of wetland) and no longer suitable for torreya to grow.
Second, in the reading, it is said that it is helpful to move torreya to a totally different place where the temperature is cooler. On the contrary, the professor asserts this way might cause negative damage to local ecology. In order to bolster her argument, the professor gives an example that once a kind of plant was moved north to a new environment and the plants spread so rapidly that they skilled a lot of other plants which had already been in danger.
Finally, the reading passage claims that torreya can be preserved in research centers, whereas the professor contends that this way cannot ensure the continued survival of torreya in the long term. this is because in order to enable torreya to resist diseases, the population need to be large and be genetically diverse. However, the research centers do not have the capacity to keep such large population of torreya.
